| Right. Furthermore, I am sure maxima is much better tested under gcl than any | |

| gcl -- it required quite a bit of effort to do so until recently. | |

| Exactly. I'll bet clisp is the slowest choice, but it has GNU readline support, | |
| which makes it about 1000 times more comfortable to use from the command line. | |

| Hey! There's a fun game. I tried your simple test on my 800 MHz Linux machine. | |
| The results are appended at the end of this message. Unfortunately, I'm a very bad | |
| benchmarker: I used different versions of maxima with each lisp implementation. | |
| (5.4 with GCL, 5.5 current cvs with CMU and 5.5 cvs as of a few weeks ago with | |
| Clisp.) I also don't have the most recent versions of GCL and Clisp. If I had a | |
| more realistic benchmark I would try a better test. | |

| The timings. Notice that I used (a+b+c+d+1)^35 instead of (a+b+c+d+1)^15; the | |
| latter was too quick. | |
| Please see the above text for disclaimers as to why this is a bad comparison. | |

| 1. On the web site you write that there is an postscript and dvi version of | |
| the documentation. Where can I find it? | |
| I have put links to the dvi and pdf version of the Maxima manual on | |
| the web page http://www.ma.utexas.edu/maxima.html | |
| I have also made a link to the latest snapshot of the sources which | |
| will be updated daily. | |
| http://www.ma.utexas.edu/users/wfs/maxima-src-snapshot.tgz | |
| 2. The Windows interface preferences does not save proxy settings. Is this | |
| disabled at the moment? | |
| The proxy settings should be saved along with your font preferences | |
| etc, if you do 'save' when in the file->preferences menu they are | |
| saved in "~/netmath.ini". I am not sure how tcl/tk interprets that | |
| under different window platforms. | |
| 3. In the src directory I found mactex.lisp . Is there a similar package | |
| available for C/C++ or standard text output for use with Excel or similar | |
| programs? | |
| Not that I know of. There is output for fortran. It should be | |
| relatively easy to write such an output function though, and a good | |
| idea to do. | |

| I don't think the different versions of maxima | |
| would influence the timing of this test. | |
| Here is some data on my 933Mhz pentium | |
| Mathematica | |
| 4.586 sec | |
| commercial macsyma 4.2 compiled in Allegro Common Lisp 6.0 | |
| (code under non-disclosure agreement. I wish I could | |
| do other things with it, but I can't...) | |
| 5.358 sec including 3.676 in garbage collection | |
| commercial macsyma 4.2 as delivered for windows system | |
| under CLOE. | |
| 27.149 sec including 24.794 in garbage collection | |
| -- seemed rather slow, so I repeated it and got | |
| even longer times, (110 sec)almost all in GC. | |
| Maxima 5.5 (using Bill's pre-packaged release) | |
| 10.37 secs in 10.37 secs elapsed time. [this seems | |
| consistent with James' time above] | |
| (I suppose I should try compiling the maxima 5.5 sources | |
| in Allegro CL, but that would take an unpredictable | |
| amount of time, perhaps 30 minutes but maybe much | |
| more if I have to start finding places to | |
| conditionalize it...) | |

| One thing you have to remember in running tests is how much space you | |
| allocate.. if you allocate for example sufficient space so that there | |
| are only a couple of garbage collections rather than 20 or 30 then | |
| obviously you get shorter times. Maxima does not by default take | |
| much space at startup since if you are doing small problems, or if it | |
| is being run on a very small machine, that would be detrimental. | |
| Normally after running for a while the space will grow, stabilizing | |
| when the percentage collected after a gc becomes reasonable. | |
| Below we run the little test on an 850 Mhz pentium, but first | |
| allocating a reasonable amount of space. | |

| in that i have changed the sysdef.lisp to load the make.lisp first | |
| so that your lisp cannot complain about redefinining the package. | |
| Also there were a few other cleanup items, that the port to cmulisp | |
| had introduced, which would have caused problems for you. Also | |
| I note in your last report you refer to 'fs' package wanted by | |
| 'cl-maxima-sysdef' : you should not be loading that file, it was | |
| for lisp machines way back when: you want sysdef.lisp like clisp | |
| and cmulisp. | |
| Ideally you make a file modelled on compile-clisp.lisp called | |
| compile-allegro.lisp, containing the allegro'isms, and so that | |
| you can make an entry | |
| echo '(progn (load "compile-clisp.lisp")(compile-maxima))' | ${CLISP} | |
| in the src/makefile | |
| let me know if you have problems... | |

| I agree that allocating space is going to affect | |
| run-times significantly. However very few people who | |
| run these programs want to know about allocation | |
| commands and CONS cells, so it is worth something to | |
| have the system be clever/adaptive. | |
| What I have done in the past is | |
| (c1)(showtime:all, ratsimp...)$ | |
| (c2) kill(all)$ | |
| but what you did is cleverer: | |
| (showtime:all, ratsimp(), 1)$ | |
| so that label (d1) is assign the number 1, rather than some huge | |
| expression. | |
| Oddly enough, the macsyma inc version seems to take | |
| longer, the 2nd time. I have to assume it is somehow keeping | |
| memory full with useless stuff... the kill(all)$ might not | |
| work. Perhaps the front end is still storing (d2) etc. | |
| If we want to give bignums a workout, instead of using | |
| (a+b+c+d+1)^35, try (1000*a+1000*b +1000*c+1000*d+1000)^35. | |
| I don't know how GCL/PARI/GNU-MP will stack up. There are | |
| excellent profiling tools in Allegro, so I can find out what | |
| percentage of time is consumed by bignum arithmetic. I suspect | |
| that many computations do not need bignums at all; the ones | |
| that use huge bignums a lot may require more delicate treatment | |
| than they are routinely given by a CAS interface. | |
| I haven't tested this recently but Maple does very very well | |
| on an example like this. But the result is not sorted in any | |
| perceptibly ordered way. The result is kind of like a hash | |
| table. The Maple advocates claim this is just fine for many | |
| purposes. True, but it is not comparable. Running the Maple | |
| sort program on the result makes Maple times comparable or | |
| slower, I think. | |
| Thanks for the compiling hints. i'll try again. | |

| unfortunately, there are a few glitches. | |
| ACL is unhappy about the redefinition of // | |
| it complains about reference to the serror package in | |
| sys-proclaim (seems I can #-allegro comment it out?) | |
| and I just commented out a function in spgcd | |
| which did some array store bogosity. | |
| I haven't figured out the dumplisp/restart | |
| sequence which for ACL6.0 is slightly different. | |
| You dump only a dll or dxl and then when you | |
| start up, | |
| you specify this file. When I do, I'll send | |
| an compile-allegro.lisp file out. | |
| It looks like the GCL speed and the Allegro | |
| speed on this problem are fairly close. Since | |
| GCL is running on a slower machine, the difference | |
| may be in GCL's favor. (I don't know if WFS | |
| has some GCL-only speedups in use on this task.) | |

| Which is slightly better but still wrong. My questions are: | |
| 1. Why doesn't maxima do the trivial integral of x? | |
| 2. How do I get it to properly change the symbol used for the | |
| integration variable and limits in multiple integrals? | |

| Which is slightly better but still wrong. My questions are: | |
| 1. Why doesn't maxima do the trivial integral of x? | |
| 2. How do I get it to properly change the symbol used for the | |
| integration variable and limits in multiple integrals? | |

| Hi, | |
| I'm looking for a maxima (version 5.4) powers function and | |
| a working version of stopex. If anyone can point me to | |
| these files, I'd appreciate it. | |
| I'm working on porting three Macsyma 422 programs to maxima; | |
| a macsyma-to-mathml translator, a second order linear DE | |
| solver, and a clone of Macsyma's specfun library (about | |
| a dozen orthogonal polynomials). Once I get them working, | |
| I'll make them freely available. | |
| Porting "back in time" twenty years is interesting; mostly | |
| I've only had to add simple utility functions such as second, | |
| op, and floor. For string functions ($stringp, $getchar, etc), I've | |
| added a few one line lisp programs. Once I spent days porting | |
| a C++ program from gcc 2.7x to gcc 2.9x; compared to that | |
| experience, porting Macsyma 422 to maxima 5.4 has so far been | |
| a breeze. | |
| Specifically: | |
| 1) I'm looking for the maxima (version 5.4) powers function; | |
| my share2 directory has a usage file for powers, but no source file. | |
| I can't find the file on maxima's cvs at the University of Texas either. | |
| If anyone can point me to the source code for powers, I'd appreciate it. | |
| 2) Maxima's stopex code seems to be broken; stopex.mc | |
| won't even load. It halts when executing | |
| EVAL_WHEN([BATCH,LOADFILE], | |
| IF GET('GNAUTO,'DIAGEVAL_VERSION)=FALSE | |
| THEN LOAD('[GNAUTO,FASL,DSK,DGVAL]))$ | |
| Commenting out this line, allows maxima to load stopex.mc. | |
| But then maxima complains that it can't find the freeofl function. | |
| Rolling my own as | |
| freeofl(x,e) := block([ ], | |
| not member(false, apply(append, [outermap(freeof, x, e)])) | |
| ); | |
| allows expandwrt to run, but it generates rubbish: | |
| (c1) expandwrt(x*(x+1),x); | |
| (d1) [5x^2+4x(x+1)] | |
| Again, if anyone has a correctly working stopex.mc file, I'd | |
| appreciate it. | |
| Thanks, | |

| I've encountered what I think are two bugs in maxima. I need to do | |
| iterated integrals of the form: | |
| f[n](x):=p[n](x)+ W(x) + integrate(f[n-1](s[n-1]),s[n-1],0,x); | |
| f[0](x):=0; | |
| where p[n](x) is a low-order polynomial (defined explicitly) and W(x) | |
| is an unknown function. I've decleared integrate linear. | |
| Here's what happens (say for p[n](x):=x): | |
| (C1) f[n](x):=p[n](x)+ W(x) + integrate(f[n-1](s[n-1]),s[n-1],0,x); | |
| (D1) f (x) := p (x) + W(x) + INTEGRATE(f (s ), s , 0, x) | |
| n n n - 1 n - 1 n - 1 | |
| (C2) f[0](x):=0; | |
| (D2) f (x) := 0 | |
| 0 | |
| (C3) declare(integrate,linear); | |
| (D3) DONE | |
| (C4) p[n](x):=x; | |
| (D4) p (x) := x | |
| n | |
| (C5) f[1](x); | |
| (D5) W(x) + x | |
| (C6) f[2](x); | |
| (D6) W(x) + (W(s ) + s ) x + x | |
| 1 1 | |
| If instead I try: | |
| (C1) declare(integrate,linear); | |
| (D1) DONE | |
| (C2) p[n](x):=x; | |
| (D2) p (x) := x | |
| n | |
| (C3) f[n](x):=p[n](x)+ W(x) + integrate(f[n-1](s),s,0,x); | |
| (D3) f (x) := p (x) + W(x) + INTEGRATE(f (s), s, 0, x) | |
| n n n - 1 | |
| (C4) f[0](x):=0; | |
| (D4) f (x) := 0 | |
| 0 | |
| (C5) f[1](x); | |
| (D5) W(x) + x | |
| (C6) f[2](x); | |
| Is x positive, negative, or zero? | |
| pos; | |
| x x | |
| / / | |
| [ [ | |
| (D6) W(x) + x + I W(s) ds + I s ds | |
| ] ] | |
| / / | |
| 0 0 | |
| (C7) f[3](x); | |
| Is x positive, negative, or zero? | |
| pos; | |
| x s x s x x | |
| / / / / / / | |
| [ [ [ [ [ [ | |
| (D7) W(x) + x + I I W(s) ds ds + I I s ds ds + I W(s) ds + I s ds | |
| ] ] ] ] ] ] | |
| / / / / / / | |
| 0 0 0 0 0 0 | |
| (C8) f[4](x); | |
| Is x positive, negative, or zero? | |
| pos; | |
| x s s x s s x s | |
| / / / / / / / / | |
| [ [ [ [ [ [ [ [ | |
| (D8) W(x) + x + I I I W(s) ds ds ds + I I I s ds ds ds + I I W(s) ds ds | |
| ] ] ] ] ] ] ] ] | |
| / / / / / / / / | |
| 0 0 0 0 0 0 0 0 | |
| x s x x | |
| / / / / | |
| [ [ [ [ | |
| + I I s ds ds + I W(s) ds + I s ds | |
| ] ] ] ] | |
| / / / / | |
| Which is slightly better but still wrong. My questions are: | |
| 1. Why doesn't maxima do the trivial integral of x? | |
| 2. How do I get it to properly change the symbol used for the | |
| integration variable and limits in multiple integrals? | |

| Greetings! I maintain the Debian package of maxima, which has | |
| recently been accepted for installation into the unstable tree. I've | |
| included Dr. Schelter's patch enabling shared (not static) linking to | |
| the system C and math libraries. With this patch, we've had a working | |
| package in incoming for some time now. | |
| Meanwhile, I forgot about maxima for a bit, upgraded my machine to the | |
| slightly newer versions of the Debian system packages, and suddenly | |
| maxima segfaults. Another Debian user sees the same thing and has | |
| filed a bug. Rebuilding on my upgraded system restores functionality. | |
| Luckily, I can chase this down if I hurry, as I still have access to a | |
| pre-upgrade machine which can build maxima with debugging symbols. | |
| I would be greatly appreciative, though, if anyone had an insight as | |
| to where to look in advance. | |
| Take care, | |

| Hi, | |
| I'm looking for a maxima (version 5.4) powers function and | |
| a working version of stopex. If anyone can point me to | |
| these files, I'd appreciate it. | |
| I'm working on porting three Macsyma 422 programs to maxima; | |
| a macsyma-to-mathml translator, a second order linear DE | |
| solver, and a clone of Macsyma's specfun library (about | |
| a dozen orthogonal polynomials). Once I get them working, | |
| I'll make them freely available. | |
| Porting "back in time" twenty years is interesting; mostly | |
| I've only had to add simple utility functions such as second, | |
| op, and floor. For string functions ($stringp, $getchar, etc), I've | |
| added a few one line lisp programs. Once I spent days porting | |
| a C++ program from gcc 2.7x to gcc 2.9x; compared to that | |
| experience, porting Macsyma 422 to maxima 5.4 has so far been | |
| a breeze. | |
| Specifically: | |
| 1) I'm looking for the maxima (version 5.4) powers function; | |
| my share2 directory has a usage file for powers, but no source file. | |
| I can't find the file on maxima's cvs at the University of Texas either. | |
| If anyone can point me to the source code for powers, I'd appreciate it. | |
| 2) Maxima's stopex code seems to be broken; stopex.mc | |
| won't even load. It halts when executing | |
| EVAL_WHEN([BATCH,LOADFILE], | |
| IF GET('GNAUTO,'DIAGEVAL_VERSION)=FALSE | |
| THEN LOAD('[GNAUTO,FASL,DSK,DGVAL]))$ | |
| Commenting out this line, allows maxima to load stopex.mc. | |
| But then maxima complains that it can't find the freeofl function. | |
| Rolling my own as | |
| freeofl(x,e) := block([ ], | |
| not member(false, apply(append, [outermap(freeof, x, e)])) | |
| ); | |
| allows expandwrt to run, but it generates rubbish: | |
| (c1) expandwrt(x*(x+1),x); | |
| (d1) [5x^2+4x(x+1)] | |
| Again, if anyone has a correctly working stopex.mc file, I'd | |
| appreciate it. | |
| Thanks, | |

| the powers function is written in lisp in Macsyma (c), and | |
| seems to be in share/ not share2/ directory. I don't | |
| if it dates back to Maxima days. I don't | |
| know why you would want to use it, because it seems to | |
| have as a feature, the bug that it requires expressions | |
| to be expanded out. You can do rat(expression,x) | |
| and then pick off the leading degree and subtract that term | |
| off, repeatedly, using ratcoeff, or bothcoeff instead. | |
| something like the (untested) program below. | |
| mypowers(r,x):= | |
| block([ h:hipow(r,x)], | |
| if h=0 then [] else cons (h, mypowers(second(bothcoeff(r,x^h)),x) | |
| ))) | |

| freeofl takes a list as first argument and ask if, for each element r | |
| of the list L, is e free of r. | |
| I would write it like this.. | |
| freeofl(L,e):= if L=[] then true else freeof(first(L),e) and | |
| freeofl(rest(L),e) | |
| I'm not sure what else is needed from the gnauto file though. | |

| Good afternoon, I had sent an earlier question to Paul S. Wang w.r.t. | |
| apparent demise of 'Macsyma' and 'PDEase' product line and he (as indicated | |
| below) referred me to you. Got time for a quick question?....Do you know to | |
| what extent both products (or their equivalent) may be available/supported | |
| in GNU project? | |
| Best Regards, | |

| Greetings! I'm upgrading the Debian maxima package to 5.5-beta, and | |
| am running into the same shared-library link problems as before. This | |
| time, I've found some time to detail what's going on a bit more | |
| clearly, so hopefully this will help. | |
| I've now produced two saved_maxima executables, one 5.5-beta compiled | |
| with -g, and one using the current cvs trees for gcl and maxima | |
| compiled as per default, both of which run successfully on 3, and | |
| segfault on 4 of our Debian 2.2 "aka potato" boxes, all of which share | |
| an NFS home filesystem. The problem is the same in all cases: on | |
| startup, | |
| PRINTstream->sm.sm_object0->s.s_dbind->sm.sm_object1->sm.sm_fp->_fileno | |
| is correctly set to stdout (1) on the boxes where it works, and | |
| garbage where it segfaults. The program segfaults when trying to | |
| first write to stdout. (Actually, the whole sm_fp FILE structure is | |
| bogus.) | |
| This setup must be preallocated on the stack or some such, as this | |
| condition holds even when breaking in gdb at the address of the first | |
| assembly statement in init of the executable. Furthermore, on | |
| checking the memory maps loaded by the process, (/proc/<pid>/maps:), | |
| all working cases show the following: | |
| 08048000-08485000 r-xp 00000000 03:03 88802 /usr/lib/maxima-5.5/src/saved_maxima_debug | |

| All machines have identical ldso and libc6 packages installed. | |
| I haven't yet had time to understand the sfaslelf.c and/or rsym_elf.c, | |
| which is where I think this is getting setup. I would greatly | |
| appreciate suggestions from those much more knowledgeable than me on | |
| this list! Unfortunately, my test case is not on a public network. I | |
| haven't yet discovered what aspect of these machines is causing the | |
| different loading, so I cannot guarantee reproducing this situation on | |
| another system, though this behavior does persist on each execution | |
| of saved_maxima here. Any suggestions of what to try would be most | |
| helpful. I'm pretty decent with C and a debugger, but don't know | |
| about elf formats, etc. | |
| Thanks! | |

| Greetings! | |
| This works! Thank you so much!!! | |
| A few (very minor in comparison) other things I've run across in | |
| putting this together: | |
| 1. Can't strip the binary: | |
| intech19:~$ strip saved_maxima | |
| BFD: /fix/g/camm/stp7tlJa: warning: allocated section `.data' not in segment | |
| BFD: /fix/g/camm/stp7tlJa: warning: allocated section `.bss' not in segment | |
| (then segfaults if run) | |
| Is this to be expected? | |
| 2. I think ctensr.mac should be named ctensr.mc? (So that it can | |
| 'load'?) | |
| 3. No manpage for xmaxima. Not a big deal. | |
| Thanks for this wonderful tool! | |

| Is there a Maxima equivalent of Macsyma's initialization file? Under | |
| Macsyma the | |
| file is called macsyma-init.macsyma. In this file, you can set filesearch | |
| and issue | |
| setupautoload statements. Maxima's info file mentions the initialization | |
| file, but | |

| Greetings! Just did an strace -f on the latest maxima, and found | |
| this: | |
| stat("init.lsp", 0xbfffd57c) = -1 ENOENT (No such file or directory) | |
| Perhaps give that a try? | |

| You can try debian statistics -- Maxima is included in the standard distro | |
| actually the most common platform is probably windows, now that there | |
| is a good self installing windows distribution (reference | |
| http://www.ma.utexas.edu/maxima.html ). I should put a counter on my | |
| page for downloads, but the thing is these things just get | |
| mirrored--something I would of course encourage not prohibit, so it is | |
| probably not worth the effort. | |

| Thanks for the help with maxima's initialization file. | |
| Using maxima 5.4 under Linux, I've only been able to get maxima to read | |
| init.lsp | |
| if the file is in the working directory. Putting it in /usr/lib/maxima-5.4 | |
| or | |
| /usr/lib/maxima-5.4/src didn't work for me. | |
| In the process of creating my init.lsp file, I discovered that maxima's | |
| save function | |
| outputs | |
| (in-package "maxima" | |
| This needs to be manually changed to | |
| (in-package "maxima") | |
| To auto-load the function "to_html" located in the file | |
| /home/barton/maxima/mathml4.3.o, the | |
| following init.lsp file works for me: | |
| ;;; -*- mode: lisp; package:maxima; syntax:common-lisp; -*- | |
| (in-package "maxima") | |
| (defprop |$to_html| #"/home/barton/maxima/mathml4.3.o" autoload) | |
| (add2lnc '|$to_html| $props) | |

| Defining "curl" to be a prefix operator makes closefile() parse as curl | |
| osefile(). Is there | |
| there a switch that changes this behavior? Specifically: | |
| (c1) prefix("curl"); | |
| (d1) "CURL" | |
| (c2) closefile("buddy.out"); | |
| (d2) CURL osefile(buddy.out) | |
| /* cl is also a prefix operator */ | |
| (c3) cl x; | |
| (c3) CURL x | |
| (I've been playing with maxima's vector packages. I may adopt it as a | |
| summer programming project.) | |

| Thank you for reporting this bug. It would appear to have been | |
| there for sometime, with people not using more than 2 character prefix | |
| (c1) prefix("curl"); | |
| (d1) "CURL" | |
| (c2) closefile("buddy.out"); | |
| (d2) CURL osefile(buddy.out) | |
| or infix operators. It can be repaired by fixing | |
| the code of read-command-token-aux in nparse.lisp as follows: | |
| [alternately you can just load in the following file..] | |
| (in-package "MAXIMA") | |
| (defun read-command-token-aux (obj) | |
| (let* (result | |
| (ch (parse-tyipeek)) | |
| (lis (if (eql ch -1) nil (parser-assoc (char-upcase ch) obj)))) | |
| (cond ((null lis) | |
| nil) | |
| (t | |
| (parse-tyi) | |
| (cond ((atom (cadr lis)) | |
| ;; INFIX("ABC"); puts into macsyma-operators | |
| ;;something like: (#\A #\B #\C (ANS |$ABC|)) | |
| ;; ordinary things are like: | |
| ;; (#\< (ANS $<) (#\= (ANS $<=))) | |
| ;; where if you fail at the #\< #\X | |
| ;; stage, then the previous step was permitted. | |
| (setq result (read-command-token-aux (list (cdr lis) )))) | |
| ((null (cddr lis)) | |
| ;; lis something like (#\= (ANS $<=)) | |
| ;; and this says there are no longer operators | |
| ;; starting with this. | |
| (setq result | |
| (and (eql (car (cadr lis)) 'ans) | |
| (cadr (cadr lis))))) | |
| (t | |
| (let ((res (and (eql (car (cadr lis)) 'ans) | |
| (cadr (cadr lis)))) | |
| (com-token (read-command-token-aux (cddr lis) ))) | |
| (setq result (or com-token res | |
| (read-command-token-aux | |
| (list (cadr lis)))))) | |
| )) | |
| (or result (unparse-tyi ch)) | |

| Subject: maxima: missing trigrat.lisp | |
| Package: maxima | |
| Version: 5.5-beta-4 | |
| Severity: normal | |
| Greetings, and thank you for your report. I'm submitting this to the | |
| Debian Bug tracking system on your behalf to better keep track of this | |
| issue. In general, there are many files in the source package which | |
| are not installed by default in the makefiles, and it appears that the | |
| installed list has gotten out of date with respect to the | |
| documentation. I'm also ccing this message to the maxima list to | |
| enquire as to whether it would be better to delete the reference to | |
| trigrat from the documentation, or to include it in the installation. | |
| Dr. Schelter, this issue has come up before with the mactex.lisp file | |
| in src/, and I just installed it by hand. Is there a general wildcard | |
| file pattern specifying files that we could *safely* install and cover | |
| any references in the existing documentation? | |
| Thanks! | |

| Subject: maxima: missing trigrat.lisp | |
| Package: maxima | |
| Version: 5.5-beta-4 | |
| Severity: normal | |
| Greetings, and thank you for your report. I'm submitting this to the | |
| Debian Bug tracking system on your behalf to better keep track of this | |
| issue. In general, there are many files in the source package which | |
| are not installed by default in the makefiles, and it appears that the | |
| installed list has gotten out of date with respect to the | |
| documentation. I'm also ccing this message to the maxima list to | |
| enquire as to whether it would be better to delete the reference to | |
| trigrat from the documentation, or to include it in the installation. | |
| Dr. Schelter, this issue has come up before with the mactex.lisp file | |
| in src/, and I just installed it by hand. Is there a general wildcard | |
| file pattern specifying files that we could *safely* install and cover | |
| any references in the existing documentation? | |
| Thanks! | |

| I would hope that the autoloading capability of the system | |
| would take care of all of the "out-of-core" files if the | |
| autoload properties were set up and the file names and locations | |
| were correct. | |
| I know of no way to assure that the different files | |
| do not tread on each others' toes, though there would probably | |
| be warning messages for overlaying already-existing program | |
| definitions. | |
| Of some interest: trigrat is NOT in the commercial macsyma, | |
| though I suspect the short file could, with a little | |
| effort, be loaded into it. I tried it and the reader-dispatch | |
| marker #$ to use the maxima reader does not work in macsyma. | |
| I'm also cc'ing Bill Gosper in case he wants to know that | |
| there are actually people fussing with the public domain | |
| maxima. | |

| Camm, | |
| Thanks for the prompt reply, | |
| I have an extra remark. | |
| I did notice also that the debian package does not depend upon the gcl | |
| debian package. I dont know if this is implicitly compiled with gcl or | |
| not. Maybe "debianized" maxima should "suggest" gcl ? | |
| About trigrat again. I find this file quite important. It is a | |
| differential relative to other simplifications in trigonometric methods. | |
| Simply ignore it in the documentation appears to me as a not good idea. | |
| Thanks again, | |
| Daniel | |

| Thank you for the report. I have corrected this in the current | |
| version, as reflected on the cvs site. | |
| and have added the following chages: | |
| 2001-04-06 Bill Schelter <[email protected]> | |
| * Fix the install to install all share/*.lisp | |
| * Fix auto-mexpr which had a bug, but only seen | |
| with 'trigrat' | |
| * Fix file_search to also look for .lisp in share/* | |
| Meanwhile you can download the file trigrat.lisp from the cvs pages: | |
| wget 'http://cvs.ma.utexas.edu/cgi-bin/cvsweb.cgi/~checkout~/maxima/share/trigrat.lisp?rev=1.2&content-type=text/plain&cvsroot=maxima' -O trigrat.lisp | |

| Hi, | |
| I just tried a cmulisp-compile with the cvs HEAD version of maxima. The | |
| files cmulisp-regex.lisp and cl-info.lisp are missing. Were they | |
| inadvertently omitted from the cvs commit? | |
| Thanks, | |
| Jim | |

| Greetings! I also just noticed the cmulisp work. What is the plan? | |
| Is work on gcl going to continue, or will it be replaced by cmulisp? | |
| Or will one have the option of either? Is there an advantage to one | |
| or the other? I only ask as to avoid any work on porting gcl to | |
| different architectures if it is likely to be replaced soon. | |
| Take care, | |

| Greetings! I also just noticed the cmulisp work. What is the plan? | |
| Is work on gcl going to continue, or will it be replaced by cmulisp? | |
| Or will one have the option of either? Is there an advantage to one | |
| The work on GCL will definitely continue, and I feel (perhaps biased | |
| of course) that GCL is the best for maxima if it is available on the | |
| platform. Having full control over GCL we are guaranteed that it will | |
| not change in ways undesirable for Maxima, and that it can be | |
| optimized for it. I know GCL does not have any memory leaks, and it | |
| is used in industry for example by the program verification, chip | |
| verification people for doing things like proving the AMD k7 floating | |
| point unit correct. This involved computations taking weeks to run on | |
| powerful processors. GCL is faster on their programs and reliable. | |
| GCL runs the basic tests in maxima about 3 times as fast as Clisp. | |
| The latter is a very good lisp, but if gcl runs on the platform I | |
| would prefer it. Personally I need the ability to single step line by | |
| line at the lisp level in debugging maxima at the lisp level, and I | |
| know how to do that in GCL (having written the code myself!), whereas | |
| I will never be as competent in someone else's lisp. | |
| However, that said, I think it is good to maintain compatibility with | |
| other lisps, so that people can use features or platforms that may be | |
| unique to those lisps, and I am very happy to see people contributing | |
| patches and making sure it does run elsewhere. | |
| And thank you for the quick fixes! They're now incorporated and | |
| uploaded in the Debian package. | |
| Thank YOU for making the debian package so up to date!! | |
| And in answer to someone else's question, maxima once built | |
| under gcl does not depend on gcl being on the system. | |

| Many thanks for all. It is the first time I send a bug report to Debian | |

| Thank you all. I am porting a program originally in Mathematica to Maxima | |

| Richard, | |
| Thank you for the sugggestion. | |
| I will do my best for it. If in the next 4 months you receive nothing: I | |
| failed, and you can send my best wishes to Stephen Wolfram :) | |
| Speaking more seriously I have with me a small group that works a lot | |
| with mathematica and if could do the job with one program I will need | |
| to convince them after all. In the meantime I will be forced to keep notes | |
| of the job. If the work seems to be fruitful I will even start to learn | |
| LISP ... | |

| Date: Mon, 12 Jun 2000 15:33:18 GMT | |
| I've encountered what I think are two bugs in maxima. I need to do | |
| iterated integrals of the form: | |
| f[n](x):=p[n](x)+ W(x) + integrate(f[n-1](s[n-1]),s[n-1],0,x); | |
| f[0](x):=0; | |
| where p[n](x) is a low-order polynomial (defined explicitly) and W(x) | |
| is an unknown function. I've decleared integrate linear. | |
| Here's what happens (say for p[n](x):=x): | |
| (C1) f[n](x):=p[n](x)+ W(x) + integrate(f[n-1](s[n-1]),s[n-1],0,x); | |
| (D1) f (x) := p (x) + W(x) + INTEGRATE(f (s ), s , 0, x) | |
| n n n - 1 n - 1 n - 1 | |
| (C2) f[0](x):=0; | |
| (D2) f (x) := 0 | |
| 0 | |
| (C3) declare(integrate,linear); | |
| (D3) DONE | |
| (C4) p[n](x):=x; | |
| (D4) p (x) := x | |
| n | |
| (C5) f[1](x); | |
| (D5) W(x) + x | |
| (C6) f[2](x); | |
| (D6) W(x) + (W(s ) + s ) x + x | |
| 1 1 | |
| If instead I try: | |
| (C1) declare(integrate,linear); | |
| (D1) DONE | |
| (C2) p[n](x):=x; | |
| (D2) p (x) := x | |
| n | |
| (C3) f[n](x):=p[n](x)+ W(x) + integrate(f[n-1](s),s,0,x); | |
| (D3) f (x) := p (x) + W(x) + INTEGRATE(f (s), s, 0, x) | |
| n n n - 1 | |
| (C4) f[0](x):=0; | |
| (D4) f (x) := 0 | |
| 0 | |
| (C5) f[1](x); | |
| (D5) W(x) + x | |
| (C6) f[2](x); | |
| Is x positive, negative, or zero? | |
| pos; | |
| x x | |
| / / | |
| [ [ | |
| (D6) W(x) + x + I W(s) ds + I s ds | |
| ] ] | |
| / / | |
| 0 0 | |
| (C7) f[3](x); | |
| Is x positive, negative, or zero? | |
| pos; | |
| x s x s x x | |
| / / / / / / | |
| [ [ [ [ [ [ | |
| (D7) W(x) + x + I I W(s) ds ds + I I s ds ds + I W(s) ds + I s ds | |
| ] ] ] ] ] ] | |
| / / / / / / | |
| 0 0 0 0 0 0 | |
| (C8) f[4](x); | |
| Is x positive, negative, or zero? | |
| pos; | |
| x s s x s s x s | |
| / / / / / / / / | |
| [ [ [ [ [ [ [ [ | |
| (D8) W(x) + x + I I I W(s) ds ds ds + I I I s ds ds ds + I I W(s) ds ds | |
| ] ] ] ] ] ] ] ] | |
| / / / / / / / / | |
| 0 0 0 0 0 0 0 0 | |
| x s x x | |
| / / / / | |
| [ [ [ [ | |
| + I I s ds ds + I W(s) ds + I s ds | |
| ] ] ] ] | |
| / / / / | |
| Which is slightly better but still wrong. My questions are: | |
| 1. Why doesn't maxima do the trivial integral of x? | |
| 2. How do I get it to properly change the symbol used for the | |
| integration variable and limits in multiple integrals? | |

| Greetings! I maintain the Debian package of maxima, which has | |
| recently been accepted for installation into the unstable tree. I've | |
| included Dr. Schelter's patch enabling shared (not static) linking to | |
| the system C and math libraries. With this patch, we've had a working | |
| package in incoming for some time now. | |
| Meanwhile, I forgot about maxima for a bit, upgraded my machine to the | |
| slightly newer versions of the Debian system packages, and suddenly | |
| maxima segfaults. Another Debian user sees the same thing and has | |
| filed a bug. Rebuilding on my upgraded system restores functionality. | |
| Luckily, I can chase this down if I hurry, as I still have access to a | |
| pre-upgrade machine which can build maxima with debugging symbols. | |
| I would be greatly appreciative, though, if anyone had an insight as | |
| to where to look in advance. | |
| Take care, | |

| Hi, | |
| I'm looking for a maxima (version 5.4) powers function and | |
| a working version of stopex. If anyone can point me to | |
| these files, I'd appreciate it. | |
| I'm working on porting three Macsyma 422 programs to maxima; | |
| a macsyma-to-mathml translator, a second order linear DE | |
| solver, and a clone of Macsyma's specfun library (about | |
| a dozen orthogonal polynomials). Once I get them working, | |
| I'll make them freely available. | |
| Porting "back in time" twenty years is interesting; mostly | |
| I've only had to add simple utility functions such as second, | |
| op, and floor. For string functions ($stringp, $getchar, etc), I've | |
| added a few one line lisp programs. Once I spent days porting | |
| a C++ program from gcc 2.7x to gcc 2.9x; compared to that | |
| experience, porting Macsyma 422 to maxima 5.4 has so far been | |
| a breeze. | |
| Specifically: | |
| 1) I'm looking for the maxima (version 5.4) powers function; | |
| my share2 directory has a usage file for powers, but no source file. | |
| I can't find the file on maxima's cvs at the University of Texas either. | |
| If anyone can point me to the source code for powers, I'd appreciate it. | |
| 2) Maxima's stopex code seems to be broken; stopex.mc | |
| won't even load. It halts when executing | |
| EVAL_WHEN([BATCH,LOADFILE], | |
| IF GET('GNAUTO,'DIAGEVAL_VERSION)=FALSE | |
| THEN LOAD('[GNAUTO,FASL,DSK,DGVAL]))$ | |
| Commenting out this line, allows maxima to load stopex.mc. | |
| But then maxima complains that it can't find the freeofl function. | |
| Rolling my own as | |
| freeofl(x,e) := block([ ], | |
| not member(false, apply(append, [outermap(freeof, x, e)])) | |
| ); | |
| allows expandwrt to run, but it generates rubbish: | |
| (c1) expandwrt(x*(x+1),x); | |
| (d1) [5x^2+4x(x+1)] | |
| Again, if anyone has a correctly working stopex.mc file, I'd | |
| appreciate it. | |
| Thanks, | |

| Is there a Maxima equivalent of Macsyma's initialization file? Under | |
| Macsyma the | |
| file is called macsyma-init.macsyma. In this file, you can set filesearch | |
| and issue | |
| setupautoload statements. Maxima's info file mentions the initialization | |
| file, but | |
| all my guesses for where to put it and what to call it have failed. | |

| Thanks for the help with maxima's initialization file. | |
| Using maxima 5.4 under Linux, I've only been able to get maxima to read | |
| init.lsp | |
| if the file is in the working directory. Putting it in /usr/lib/maxima-5.4 | |
| or | |
| /usr/lib/maxima-5.4/src didn't work for me. | |
| In the process of creating my init.lsp file, I discovered that maxima's | |
| save function | |
| outputs | |
| (in-package "maxima" | |
| This needs to be manually changed to | |
| (in-package "maxima") | |
| To auto-load the function "to_html" located in the file | |
| /home/barton/maxima/mathml4.3.o, the | |
| following init.lsp file works for me: | |
| ;;; -*- mode: lisp; package:maxima; syntax:common-lisp; -*- | |
| (in-package "maxima") | |
| (defprop |$to_html| #"/home/barton/maxima/mathml4.3.o" autoload) | |
| (add2lnc '|$to_html| $props) | |

| Dear maxima users | |
| I am trying to start using maxima. After I compiled gcl-2.3.8 and | |
| maxima-5.4 I am trying to get some plots. But when I tried something | |
| like: | |
| plot2d(sin(x),[x,-5,5]); | |
| or | |
| plot3d(2^(-u^2+v^2),[u,-5,5],[v,-7,7]); | |
| the screen is completely full of data but any graphic appear. I thought | |
| that maxima had the possibility to use Tcl/tk in order to plot graphics | |
| on the screen, but it doesn't work for me. What am i doing wrong ? | |
| I tested gcl (tcl-tk) doing | |
| > (si::tkconnect) | |
| > (load "/usr/local/lib/gcl-2.3.8/gcl-tk/demos/widget.lisp") | |
| and it worked pretty well. I have in my linux box: | |
| tcl-8.3.2-4mdk | |
| tk-8.3.2-4mdk | |
| tclx-8.3.2-4mdk | |
| How can I get plots from maxima ? For me, it is not necessary to use an | |
| interface it would be suficient enough to produce gnuplot format output, | |
| or whatever it was. | |
| Please reply directly the answers to me because I am not subscribe to | |
| this list. | |
| Thank you in advance for your help. | |

| At the end it was a problem in the omplotdata file, for recent | |

| Hi, | |
| I just tried a cmulisp-compile with the cvs HEAD version of maxima. The | |
| files cmulisp-regex.lisp and cl-info.lisp are missing. Were they | |
| inadvertently omitted from the cvs commit? | |
| Thanks, | |

| Greetings! I also just noticed the cmulisp work. What is the plan? | |
| Is work on gcl going to continue, or will it be replaced by cmulisp? | |
| Or will one have the option of either? Is there an advantage to one | |
| The work on GCL will definitely continue, and I feel (perhaps biased | |
| of course) that GCL is the best for maxima if it is available on the | |
| platform. Having full control over GCL we are guaranteed that it will | |
| not change in ways undesirable for Maxima, and that it can be | |
| optimized for it. I know GCL does not have any memory leaks, and it | |
| is used in industry for example by the program verification, chip | |
| verification people for doing things like proving the AMD k7 floating | |
| point unit correct. This involved computations taking weeks to run on | |
| powerful processors. GCL is faster on their programs and reliable. | |
| GCL runs the basic tests in maxima about 3 times as fast as Clisp. | |
| The latter is a very good lisp, but if gcl runs on the platform I | |
| would prefer it. Personally I need the ability to single step line by | |
| line at the lisp level in debugging maxima at the lisp level, and I | |
| know how to do that in GCL (having written the code myself!), whereas | |
| I will never be as competent in someone else's lisp. | |
| However, that said, I think it is good to maintain compatibility with | |
| other lisps, so that people can use features or platforms that may be | |
| unique to those lisps, and I am very happy to see people contributing | |
| patches and making sure it does run elsewhere. | |
| And thank you for the quick fixes! They're now incorporated and | |
| uploaded in the Debian package. | |
| Thank YOU for making the debian package so up to date!! | |
| And in answer to someone else's question, maxima once built | |
| under gcl does not depend on gcl being on the system. | |

| Fateman asks: | |
| GCL looks to be pretty fast there! | |
| Is there any c-code for the polynomial/rational function | |
| stuff in Maxima? (In the original code I think | |
| There is c code for ctimes, cplus, and cmod (the integer parts of | |
| polynomial times), which is put on as an optimizer. I just tried an | |
| experiment of removing that code and just putting in the standard | |
| common lisp function proclamations as in sys-proclaim.lisp. | |
| The time went from 2.81 seconds to 2.94 seconds (both were elapsed | |
| time = run time since machine was unloaded), so I guess the | |
| optimizations help a little bit (4.4%). When I originally wrote the C | |
| versions [many years ago!], I had not yet implemented the very fast | |
| function calling of functions with a fixed number of arguments in GCL, | |
| which required my garbage collection of the C stack in GCL etc: Such | |
| functions now compile to c functions of the same number of arguments | |
| and the calls are made via the c stack or via registers depending on | |
| the compiler, and so they are fast, with the only overhead over | |
| regular C being one memory look up since the function call is of the | |
| form (*faddr)(a,b,c) instead of f(a,b,c). Basically there is not much | |
| you can do in C that you can't do in lisp if you understand the | |
| compiler.. Of course since I was the one who did the original version | |
| of gcc for the x86, I do understand both the lisp and c compilers | |
| which of course is one reason I personally like the | |
| maxima->gcl->gcc->assembler chain! Of course our bignum code | |
| is still not so optimal, when I was redoing the bignum code of GCL | |
| last time the good GNU mp bignum code did not exist. Also the | |
| ability of gcc to handle long long 's did not exist. So there is | |
| definitely room for improvement. | |

| I just began to run my favorite tests for | |
| computer algebra systems in maxima 5.5 beta3, after | |
| having tried: | |
| (a+b+c+d+1)^35 | |
| on my linux box | |
| (amd k6-2 at 300 MHz, 256 MB ram, | |
| 512 MB swap, Mandrake 7.1): 21 seconds. | |
| (By the way, | |
| 1. Maple V.5.1 cannot do the job: | |
| Error, (in expand/bigpow) | |
| object too large | |
| 3,869 | |
| 2. MuPAD 2.0 succeeds in 401s after | |
| _at least_ one reinitialization of the kernel | |
| (doubling the stack for pari?) | |
| 3. pari/gp 2.1 succeeds in 97s with a big initial stack | |
| ) | |
| The problem: | |
| ------------ | |
| I am very confused by the result of | |
| integrate(1/(1+x^5+x),x); | |
| which is, in my opinion, false and very strange, without | |
| any warning. | |
| Best regards. | |

| The code for rational function integration in Maxima has been | |
| replaced in the commercial macsyma. Basically, if the denominator | |
| of the rational fraction does not factor over the integers, | |
| then newer solution methods have been discovered. These are | |
| actually kind of clumsy with sum over "rootof" expressions, but | |
| the answer is formally correct. Mupad uses these methods. | |
| There are other, probably better for many users, ways for expressing the | |
| answer.. e.g. finding approximate roots in the complex plane | |
| in this case (where the denominator has no extra parameters). | |
| If the derivative doesn't come back with the same answer, | |
| after simplification, then there may also be a bug in | |
| the procedures. | |

| * I have made some changes to Maxima to handle the integrals | |
| with irreducible factors, see below. | |
| * Also I have changed GCL to compile Maxima on optimize, so that the | |
| test now takes 2.46 seconds rather than 2.81 as previously stated.. | |
| [this is 850Mhz Pentium III under linux, gcc 2.95.2, GCL 2.3.8 beta3 | |
| with sufficient space allocated] | |
| (C1) :lisp (progn (allocate 'cons 8000 t) (allocate 'fixnum 1000 t) (si::allocate-relocatable-pages 2000 t)) | |
| (C1)(showtime:all, ratsimp((a+b+c+d+1)^35),1)$ | |
| Evaluation took 2.46 seconds (2.49 elapsed) | |
| ====== | |
| Details about the integration change: | |
| I have added a switch so that the integration in the term | |
| of sum over the roots of the denominator, will be enabled. | |
| Below is a sample call. This is in the latest snapshot. | |
| One needs several files to bring this uptodate including sinint, | |
| displa, and some others.. | |
| (C3) describe(rootso); | |
| - Variable: INTEGRATE_USE_ROOTSOF | |
| default: [false] If not false then when the denominator of an | |
| rational function cannot be factored, we give the integral in a | |
| form which is a sum over the roots of the denominator: | |
| (C4) integrate(1/(1+x+x^5),x); | |
| / 2 | |
| [ x - 4 x + 5 | |
| I ------------ dx 2 x + 1 | |
| ] 3 2 2 5 ATAN(-------) | |
| / x - x + 1 LOG(x + x + 1) SQRT(3) | |
| (D4) ----------------- - --------------- + --------------- | |
| 7 14 7 SQRT(3) | |
| but now we set the flag to be true and the first part of the | |
| integral will undergo further simplification. | |
| (C5) INTEGRATE_USE_ROOTSOF:true; | |
| (D5) TRUE | |
| (C6) integrate(1/(1+x+x^5),x); | |
| ==== 2 | |
| \ (%R1 - 4 %R1 + 5) LOG(x - %R1) | |
| > ------------------------------- | |
| / 2 | |
| ==== 3 %R1 - 2 %R1 | |
| 3 2 | |
| %R1 in ROOTSOF(x - x + 1) | |
| (D6) ---------------------------------------------------------- | |
| 7 | |
| 2 x + 1 | |
| 2 5 ATAN(-------) | |
| LOG(x + x + 1) SQRT(3) | |
| - --------------- + --------------- | |
| 14 7 SQRT(3) | |
| (C7) | |
| Note that it may be that we want to approximate the roots in the | |
| complex plane, and then provide the function factored, since we | |
| will then be able to group the roots and their complex conjugates, | |
| so as to give a better answer. | |

| Evaluation took 2.74 seconds (3.18 elapsed) | |
| The time tends to increase, but it's now much faster when I allocated more | |

| The C compiler is egcs-2.91.66 but I'm not quite sure how much that | |

| A better test for Maxima speed, if you are | |
| concerned with the speed of polynomial and | |
| rational function manipulation, may be this: | |
| (showtime:all, rat( (a+b+c+d+1)^35), 1)$ | |
| note that instead of doing ratsimp, we are | |
| doing rat. | |
| What ratsimp does is take the result of | |
| the tightly encoded polynomial result of rat and | |
| conses up an algebraic tree, in macsyma's | |
| "general form". | |
| This does a sorting / ordering kind of | |
| operation which is rather expensive. | |
| In particular, I just tried using MAXIMA source on | |
| Allegro CL on a 933 Mhz machine. rat alone takes | |
| about 0.94 seconds. | |
| (the commercial macsyma takes 1.2 sec + another 7.5 in | |
| garbage collection). | |
| Doing the RATSIMP takes 4.65 seconds. | |
| The Allegro profiler (is there one for GCL?) | |
| gives this information, which shows that the largest | |
| single user of computer time is the | |
| 8% of the time in the RATSIMP taken within the | |
| function MEMQ. | |

| 1.4 93.7 0.0 0.0 "qcons" | |
| 1.2 94.9 0.0 0.2 CPLUS | |
| 1.0 96.0 0.0 0.0 "replace_temp_bignum" | |
| [1] CL-MACSYMA(22): | |
| .............. | |
| So a good place to try to improve this code is | |
| either in making kf_bignum_multiply faster, [or to | |
| eliminate calls to it]. Another place is pzerop. | |
| This is defined as | |
| (defun pzerop (x) (and (numberp x) (zerop x))) | |
| which suggests it could | |
| (a) be done in-line and/or | |
| (b) done faster e.g. (defun pzerop(x)(equalp x 0)) | |
| It is plausible that PCTIMES and PTIMES are | |
| taking a lot of time: PCTIMES multiplies | |
| a polynomial by a coefficient (which could | |
| be a polynomial in other variables), and | |
| PTIMES. CTIMES and CPLUS are in there, but | |
| not as big contributors. | |

| Camm> Greetings! I also just noticed the cmulisp work. What is the plan? | |
| Camm> Is work on gcl going to continue, or will it be replaced by cmulisp? | |
| Camm> Or will one have the option of either? Is there an advantage to one | |
| Camm> or the other? I only ask as to avoid any work on porting gcl to | |
| Camm> different architectures if it is likely to be replaced soon. | |
| While I can't speak for maxima itself, I plan to make the necessary | |
| changes to get maxima to run on cmulisp. In fact, I've just sent | |
| (privately, since I wasn't on this list until just now) a set of | |
| patches (done by Fred Gilham and me) that lets cmulisp run all of the | |
| tests correctly. cmulisp can now also do plotting via the openmath | |
| plotting option. | |
| Also, since gcl runs on far more platforms than cmulisp, I hope gcl | |
| continues so that maxima continues. | |
| Ray | |
| P.S. I was trying to rebuild the info files. SpecfunII.texi seems to be | |
| missing.... | |

| Dear friends of maxima, | |
| The use of maxima under xemacs is quite comfortable. | |
| However, I tried xmaxima 5.5 and found it beautiful. | |
| I tried to change the dimensions of the window, | |
| but failed miserably : I'm just a beginner in Tkl/Tk. | |
| However I found the following : | |
| - the A4 format (used in Europe) is 21cm x 29.7cm, | |
| that is 8.2777" x 11.6929", not, of course 8" x11" | |
| - in line 11916, the preferences file is spelled "~/xmaxina.ini" | |
| and not "~/xmaxima.ini". | |
| (In my opinion, "~/.xmaxima.ini" would be preferable, | |
| preventing any deleting by mistake) | |
| - also, for the moment, there is no other option than the font size. | |
| Can _a user_ add other preferences, and how? | |
| Best regards. | |

| I grabbed yesterdays sources and there are a few problems. | |
| o First, it fails in rtest3a with trying to eval some ill-formed | |
| expression. The changes looked fairly minimal, but I think the | |
| problem is in mstuff.lisp. The definition of mfunction1 changed. | |
| If I change it back to the original, that error doesn't occur | |
| anymore. | |
| o The following patch is required. Otherwise problems 2 and 5 of | |
| rtest1a returns 0 where FALSE is expected. | |

| o A typo in compile-cmulisp: (setq *init-run*) should probably be | |
| (setq *init-run* t). | |
| o In generr.lisp, the errset macro used for clisp can also be used for | |
| CMUCL. If not, then errcatch doesn't catch errors as desired. | |
| (Note: If you change generr, the files that use errset don't get | |
| recompiled by make. I think they should.) | |
| o Finally, a more serious problem. Problems 6 and 23 in rtest6a | |
| are wrong. For problem 23, the expected answer is abs(y). However, | |
| I get just plain y. Similarly in problem 23, the abs is missing. | |
| For some reason radexpand is ALL instead of TRUE. (Note: the | |
| documentation for SQRT is wrong. It says if RADEXPAND is TRUE, | |
| sqrt(x^2) is x. This only happens if RADEXPAND is ALL.) | |
| With these minor changes, all of the tests pass on CMUCL, except for | |
| the last noted problem. These go away too if RADEXPAND is set to | |
| TRUE. | |

| I grabbed yesterdays sources and there are a few problems. [under cmulisp] | |
| Thank you for testing that. I have fixed the things you suggest | |
| that presented problems under cmulisp and also the problem | |
| o Finally, a more serious problem. Problems 6 and 23 in rtest6a | |
| are wrong. For problem 23, the expected answer is abs(y). However, | |
| should now be ok. hyp.lisp was setting the value not inside a let. | |
| All the tests are now ok under gcl and clisp. Also the source level | |
| debugging (which had temporarily been broken by a clisp patch), does | |
| now work under both gcl and clisp. All the emacs files such as | |
| dbl.el, smart-complete.el, sshell.el are also now in the maxima | |
| distribution as well as the gcl distribution, since people using clisp | |
| or cmulisp would also need them if they want the source level | |
| debugging under emacs. I have also updated the documentation on | |
| that (as well as a number of other things). | |
| The changes are in the cvs and also the daily snapshot has been | |
| updated. | |

| Hello, | |
| I have written some 'complete idiot's guide to Maxima-mode in Emacs' | |
| (don't laugh, it took me hours to figure that out). I thought I'd better | |
| ask first for comments before announcing it to the public. | |
| Have a look at | |
| http://symaxx.sourceforge.net/MaximaMode_in_Emacs.html | |
| and tell me, what you think. I know almost nothing about Emacs, so | |
| please correct me if I'm wrong or there is an easier way. | |
| I was planning to post the link on sci.math.symbolic at some time. | |
| Regards | |
| Markus | |

| How can I perform ``plot3d()'' of a matrix? | |
| I need to get the plot of a 3d-grid (surface) defined by a matrix in which | |
| elements represent Z-coordinates for 3d-grid nodes. | |
| I tried the way described below: | |
| M:MATRIX([1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4])$ | |
| plot3d(M[x][y],[x,1,4],[y,1,4],['grid,4,4]); | |
| But I got the error message from the Maxima in which it said that the ``x'' | |
| and ``y'' in the ``M[x][y]'' expression must be integers. That's right, but I | |
| can not find a function that converts float numbers to integer ones. | |
| I also tried to fool the Maxima by typing something like this: | |
| plot3d(M[?truncate(x)][?truncate(y)],...); | |
| but got the error message about my ``x'' and ``y'' are not floats (but what | |
| they are if they aren't integers too?). The straightforward way to fix this: | |
| plot3d(M[?truncate(FLOAT(x))][?truncate(FLOAT(y))],...); | |
| produces the same error message :( | |
| Any solution out there? | |
| Thanks a lot for any help... | |
| P.S. | |
| I think my problem is enough foolish, but I'm C/C++/asm programmer and these | |
| implicit dynamical type convertion tricks produce the cold sweat on my | |
| forehead ;) | |

| Somewhat off-topic, but if you are writing a DE final examination this | |
| weekend, you may | |
| enjoy the short Maxima program: | |
| gen_de(sol, dvar, ivar, const) := block([de ], | |
| sol : [sol, diff(sol,ivar),diff(sol,ivar,2)], | |
| de : eliminate(sol, const), | |
| de : solve(de, diff(dvar,ivar,2)), | |
| ratsimp(first(de)) | |
| )$ | |
| (c1) depends(y,x)$ | |
| (c2) gen_de(y=k1*(x+x^3)*x^(-3/2) + k2 * x*x^(-3/2),y,x,[k1, k2]); | |
| (c3) 'diff(y,x,2) = 3*y/(4*x^2) | |
| (c4) latex(%); | |
| $$ \frac {d^{2} y}{d x^{2}}=\frac {3\,y}{4\,x^{2}} $$ | |
| Wunderbar. To me Maxima is fun, but it also about doing real work quickly and accurately. | |
| For all the folks that have made this possible, I thank you. | |

| How can I perform ``plot3d()'' of a matrix? | |
| I need to get the plot of a 3d-grid (surface) defined by a matrix in which | |
| elements represent Z-coordinates for 3d-grid nodes. | |
| I tried the way described below: | |
| M:MATRIX([1,2,3,4],[1,2,3,4],[1,2,3,4],[1,2,3,4])$ | |
| plot3d(M[x][y],[x,1,4],[y,1,4],['grid,4,4]); | |
| I think the easiest thing to do is to define a function f, which is | |
| what you want to plot: ie f(x,y) == z where the z is what you want: | |
| f(x,y):=float(M[?round(x),?round(y)])$ | |
| plot3d(f,[x,1,4],[y,1,4],['grid,4,4]); | |
| then plot3d works ok. The problem with putting random forms in as the | |
| first argument of plot3d, is that plot3d evaluates its arguments, | |
| [perhaps it should not but it does..]. | |
| And it is not happy evaluating ?round(x) until that has a value.. | |
| Note also while M[1][2] will work, M[1,2] will probably be more | |
| efficient not that that matters too much here.. | |

| I recently downloaded the PC version of maxima and have been having a | |
| lot of fun playing with it. | |
| I used to use Macsyma, many years ago, so it was good to remeber some of | |
| that stuff. | |
| However, I do not seem to be able to get WRITEFILE to work. | |
| If I submit a series of commands like: | |
| WRITEFILE("TRANSCRIPT"); | |
| x: a + b; | |
| CLOSEFILE(); | |
| then maxima creates a file called TRANSCRIPT, but it is empty. | |
| Is this a known weakness of the PC distribution or am I missing | |
| something. | |
| Thanks for your help | |

| A (partial) answer to a question I asked, | |
| for persons with the same problem (if any?): | |
| The option "-geometry" seems not to work | |
| (or I invoke bad parameters? | |
| xmaxima -geometry 950x700 | |
| (then, an order | |
| puts "${width}x${height}" | |
| before the dsetq of line 12007 | |
| gives an error message). | |
| These lines around 12007 automaticaly set width and height | |
| to a maximum, which are a bit too big for me. | |
| So, a not so bad workaround to get useful geometry | |
| is to write | |
| geometry . 950x700+10+30 | |
| instead of | |
| geometry . "${width}x${height}" | |
| Best regards. | |

| Only think I noticed that you are using <control-alt-a> notation, where | |
| emacs would simply say C-M-a. As you are explaining what to press at | |
| the beggining, anyway, you should probably use emacs notation. | |

| 2) It is the first speed-test I always try (it is not too good, | |
| but it is easiest). | |
| 3) (The most important) I think I am doing something wrong with | |
| my configuration, and would like to mend it. | |
| 4) In fact, I cannot print it even if I multiply the bignum | |
| stack and get enough space... | |

| I have made a few changes to the printing of bignums in maxima so it | |
| now handles the 10000! ok. (see cvs or snapshots). | |
| Still as I said before the GCL bignum code is not so good, since the | |
| 10000! takes 5 seconds on a pentium 850mhz, and another 5 seconds to | |
| print (with GCL). The maxima CLISP time (using GMP bignum code) is MUCH | |
| faster (0.12 seconds to compute it) with printing taking 3 seconds. | |
| I will look into putting the GMP bignum code into GCL as well. | |
| ====== | |
| Also the xmaxima is mostly working in clisp and cmulisp now. | |

| I made a while back GNU readline support for GCL-2.3 and all programs | |
| using GCL like Maxima. Back then I needed to link readline statically, and | |
| it worked fine. | |
| Now I'm porting the patch to GCL-2.3.8 and it seems that readline gets | |
| linked dynamically just fine. Nevertheless, it seems that my code in GCL | |
| gets linked in "statically"--which means that my initialization routine, | |
| which initializes Readline variables, gets called only while GCL is being | |
| compiled. But when the user later actually runs GCL, the readline | |
| variables are resetted and it doesn't work. | |
| So, I should ensure that some C-function would be called when GCL is | |
| actually run, after compilation. stracing saved_maxima it seems that it | |
| might run "init.lsp" at the startup. So I could register a C function | |
| as a LISP command and call my initialization routine from | |
| init.lsp. However this might not be ideal solution, since it wouldn't be | |
| transparent to GCL user. | |
| How could I trigger my C function at Maxima load time (instead of compile | |
| time)? | |

| Bugs: | |
| 1) Maxima's (gcl / maxima 5.5 and 5.4) abs and cabs functions need some | |
| work: | |
| (C1) display2d : false$ | |
| (C2) cabs(%i + log(1+%i)); | |
| (D2) SQRT(LOG(2)^2/4+1) | |
| (C3) cabs(rectform(%i + log(1+%i))); | |
| (D3) SQRT(LOG(2)^2/4+(%PI/4+1)^2) | |
| /* (D3) is correct and (D2) isn't. */ | |
| Maxima 5.5 is missing the eigenvalue code, but Maxima 5.4 has it. Under 5.4, I get | |
| another problem with cabs: | |
| (c1) tee[i,j] := if(i=j) then %i-2 else if (abs(i-j)=1) then 1 else 0$ | |
| (c2) m : genmatrix(tee,4,4)$ | |
| (c3) cabs(first(first(eigenvalues(m)))); | |
| This above gives an error about "SIGN called on ... (I'm connected to my NT machine | |
| now and I don't remember the exact error. Sorry.) | |
| 2) A bug with trigreduce: | |
| (C11) trigreduce(cos(2*atan(8/5)/3)); | |
| Error: 8 is not of type LIST. | |
| Fast links are on: do (si::use-fast-links nil) for debugging | |
| Error signalled by MACSYMA-TOP-LEVEL. | |
| Broken at MACSYMA-TOP-LEVEL. Type :H for Help. | |
| MAXIMA>>:q | |
| (Incidentally, isn't "signaled" the correct spelling? Lotus Notes seems to think so.) | |
| 3) Might a bug or might be a feature, but float doesn't evaluate %pi to a float while bfloat does: | |
| (C15) float(%pi); | |
| (D15) %PI | |
| (C16) bfloat(%pi); | |
| (D16) 3.141592653589793B0 | |
| (C17) float(%e); | |
| (D17) %E | |
| (C18) bfloat(%e); | |
| (D18) 2.718281828459045B0 | |
| (Under Macsyma 422, float(%pi) and float(%e) both evaluate to floats.) | |

| Hello, | |
| I'm a newbie in maxima. | |
| I would like to use Hermite Polynomials. | |
| It seems from documentation that they are incuded in the specint | |
| package (%HE). | |
| But I have not be able to obtaine them ... | |
| Any hints ? | |
| Thanks a lot, | |
| ps: I use the potato .deb version of maxima | |

| Code for Hermite polynomials (along with about 15 other orthogonal | |
| polynomials) is in the specfun package. I contributed this package in | |
| mid-April, so unless your maxima | |
| is very recent, you won't have it. You can download specfun.mc from the | |
| maxima CVS at | |
| http://cvs.ma.utexas.edu/cgi-bin/cvsweb.cgi/maxima/share/?cvsroot=maxima | |
| Copy specfun.mc to the maxima share directory. For best performance, compile specfun. | |
| To use it, try | |
| (C4) load("specfun")$ | |
| (C5) display2d : false$ | |
| (C6) makelist(hermite(i,x),i,0,3); | |
| (D6) [1,2*x,-2*(1-2*x^2),-12*x*(1-2*x^2/3)] | |
| Let me know if you have any problems. | |
| Since contributing specfun, I've made a few improvements to it (improved | |
| the gradef | |
| statements and sped up the spherical harmonic function). I'll send the | |
| newest version to anybody that wants it (it's small -- about 20K). My | |
| package also has two demonstration programs -- variational method in | |
| quantum mechanics and a first order degenerate pertubational calculation | |
| for the Stark effect. | |

| I have Hermite polynomials in version 5.5-beta3. | |
| You have to load the package | |
| "specfun" | |
| and use them via | |
| hermite(n,x) | |
| where I suppose (I do not know for sure) 'n' is a number and 'x' is | |
| a variable. | |
| Sorry but I do not know those polynomials... :-) so maybe this is | |
| not what you are looking for. | |

| Dear MAXIMA users, | |

| such integrals as | |
| integrate(x^3/(exp(x)-1),x,0,INF), | |
| in this particular case the result should be %pi^4/15. MAXIMA returns: | |

| I have finally gotten around to adding much better bignum code to GCL. | |

| take... The times are on a 900Mhz pentium III. | |
| I have just put out gcl 2.4.0 and maxima 5.6 | |
| Please let me know of problems in compiling this. I have not yet put | |

| Thank you, Bill, for your magnificent work. | |

| Incidentally, 10000! is computed and printed without any call of | |
| :lisp(si ... etc... in maxima 5.6 on my machine | |
| (roughly as fastly as under pari/gp 2.1.1). | |
| However I tried to compute one more time (1+a+b+c+d)^35, | |
| and interrupted maxima twice. Then I noticed that | |
| there were 2 copies of saved-maxima in memory, computing | |
| hard (98% of CPU time). Is this a feature or a bug ;-)? | |
| Best regards. | |

| I have just started using xmaxima frontend and would like to have plots | |
| in a separate window. Where do I set this up? | |
| In File->Preferences | |
| Where it asks | |
| Should plot windows be embedded ? | |
| click on embedded and change it to one of the other defaults: | |
| separate means it will reuse one external popup window | |
| multiple means it will make a new window for each plot. | |
| You should be able to then save your preferences. Then you should | |
| reboot windows -- no just kidding..! | |
| This may not be in older versions of xmaxima/netmath | |

| wget http://cvs.ma.utexas.edu/cgi-bin/cvsweb.cgi/~checkout~/maxima/bin/xmaxima?rev=1.3&content-type=text/plain&cvsroot=maxima --output-document=xmaxima | |
| I cant be sure it will be compatible with the maxima binary you have, | |
| but it probably is. You need to set an environment variable to tell | |
| xmaxima which maxima executable to use, ie where the root maxima | |
| directory is eg under unix: | |
| export MAXIMA_DIRECTORY=/home/wfs/maxima-5.6 | |
| xmaxima | |
| Note if you are running the clisp version of maxima you would use the | |
| same as the above but do | |
| xmaxima -lisp clisp | |
| this last will certainly only work with maxima 5.6. | |

| I have a couple questions about the plot window. | |
| The reason I ask is eventually (when I both figure out | |
| how and have time) I hope to create a GTK-Perl based | |
| interface to maxima (the embryonic beginnings of this | |
| are on sourceforge at | |
| http://mathshield.sourceforge.net) using MathML and a | |
| notebook style interface. At some point I'm hoping to | |
| embed the plot window in the notebook. Is the | |
| embedding ability specific to TCL, or could it | |
| theoretically be done with other toolkits? Will I | |
| need to do some lower level coding to avoid dependance | |
| on TCL in the plot window itself? | |
| (http://mathshield.sourceforge.net/concept2.png is a | |
| rough idea of where I hope to go eventually with this | |
| - the screenshots section shows a little more of the | |
| current interface idea if anyone is interested.) | |
| Thanks for your tremendous work on all of this by the | |
| way. Maxima is one of the coolest software programs | |
| I've seen in a long time. | |
| Oh, inexperienced newbie question. Does anyone know | |
| how the feature sets of Octave and Maxima compare? I | |
| don't have enough experience with Octave to know. | |
| Anyone worked with them enough to make a comparison? | |

| One thing you might look at is the TeXmacs. Maxima has an interface | |
| with that, which is interesting. Needs some work, but it does | |
| typesetting of the math. I also will be putting an interface into | |
| xmaxima that displays properly typeset output. | |
| Displaying a plot window inside another application is easy enough: | |
| If you are doing it under X windows at least then for example | |
| do | |
| xwininfo | |
| to find the id of the window you are interested in. | |
| suppose it has id 0x100001a | |
| % wish -use 0x100001a -f foo.tcl | |
| where | |
| foo.tcl is | |
| ======= | |
| label .l -text {hello world} | |
| pack .l | |
| ===== | |
| will put that window into the one you specified which perhaps | |
| belongs to another application. The plotting stuff is all in | |
| the files: plotting.tcl | |
| In the xmaxima.tcl you want the stuff starting at | |
| ## source plotting.tcl | |
| down to | |
| ## endsource plotting.tcl | |
| -use id | |
| Specifies that the main window for the | |
| application is to be embedded in the | |
| window whose identifier is id, instead | |
| of being created as an independent | |
| toplevel window. Id must be specified | |
| in the same way as the value for the | |
| -use option for toplevel widgets (i.e. | |
| it has a form like that returned by | |
| the winfo id command). | |

| Octave is a clone of Matlab. Essentially, it does | |
| "numbers". Maxima does "symbols" which as a special | |

| As far as I know, one can compute 10000! and even 50000! by | |
| assigning more memory to bignums: | |
| :lisp(si::multiply-bignum-stack 100) | |
| lets one compute 10000! (do not know if 50000! also). | |
| This is all in a Pentium 133Mmx (1 minute to compute+display) | |

| No problem. Most advanced users of maxima will find | |
| MathShield cumbersome and useless, so I don't blame | |
| you for asking. I'm targeting this for people like | |

| The way I hope to work this will be somewhat similar | |
| to the way Mathematica has done it, i.e. formatting | |
| things like fractions, square roots, exponents and | |
| integral signs, while allowing people to enter text | |
| commands when it suits their purpose (like | |
| programming.) From the mathml, perl scripts can then | |
| be used to process the expression down into maxima | |
| syntax, and then the same process in reverse can | |
| translate certain parts of the answer into MathML | |
| (leaving some as text) and send the to the display | |
| widget. For example, if I were entering an expression | |
| with multiple fractions, exponentials within | |
| exponentials, and other such fun complexities, I would | |
| want to see it displayed in a formatted form in order | |
| to better keep track of it. However, for other things | |
| like writing macsyma programs, you are correct in | |
| saying that Mathml would be useless and a hinderance, | |
| so in those instances the Mathml would give way to | |
| pure text entry, which would still be allowed. | |
| Basically this is aimed at making a few of maxima's | |
| abilities easier to use (at least for a user like me) | |
| while hopefully not making more advanced usage | |
| impossible. | |
| The reasons I picked MathML specifically are that | |
| there has already been some work done on a GTK display | |
| widget for MathML called GTKMathView and the hope that | |
| MathML abilities in Mozilla would eventually open up | |
| some possibilities for easy display of math notebooks | |
| on the web. | |
| So that's the idea - to add formatting where it is | |
| helpful and add some graphical tools for people who | |
| (like me) are bad at remembering the syntax rules. | |
| Maybe a good analogy would be the Lyx program - most | |
| advanced users use raw latex or tex because they have | |
| more power and options, but a lot of people use Lyx | |
| because it makes things simpler for them and their | |
| needs are modest. Lyx allows TeX expressions, but | |
| also provides buttons for basic functionality. I've | |
| use Lyx quite a bit, and I've found I like that | |
| approach. You can start out doing things slowly with | |
| the graphical buttons, but the equations are entered | |
| as equations with immediate visual feedback rather | |
| than long, cryptic text strings and as you gradually | |
| learn the TeX commands you get faster. To me, it | |
| seems like a good way for beginners to approach maxima | |
| too. Whether I can pull it off or not is something | |
| else again, but it never hurts to try and the worst | |
| that will happen is that I'll know more rather than | |
| less. :-) | |

| I believe that Mathematica does not use MathML, though | |
| it is willing to produce it if you wish. There is a | |
| protocol used for communicating between front and | |
| back ends of Mathematica (mathtalk?) and there is | |
| also a protocol with Maple (or used to be... Irena, | |
| I think), and the commercial Macsyma uses some kind | |
| of Lisp, plus some signalling mechanism. You have | |
| no signalling mechanism, and perhaps don't understand | |
| why you need it. | |

| If you are writing the front end, why not just have | |
| the front end talk to the back end in something that | |
| the back end already understands. There are two | |
| obvious choices: the macsyma command language and the | |
| underlying lisp. You are just making more work | |

| mathml and a translator out. You are also increasing | |
| the bandwidth requirements by a factor of 50 or so as | |
| well as lacking vital communication protocols, which | |
| you presumably would just make up in some non-standard | |
| way. | |
| There are also programs to display math in typeset | |
| form (in lisp, and also see MINSE/glyphd, which I am using, | |
| which produces little GIFs for human consumption). | |

| There is already math display (even conversion into | |
| TeX) in maxima. Are you going to go through every | |
| construction in Maxima and convert it into MathML? Guess | |
| what... not everything in Maxima has a MathML encoding. | |
| And are you going to convert everything in MathML into | |
| Maxima? Guess what... some things may not be in Maxima. | |

| Not a different command structure - I actually like | |

| I'm probably missing something there. I was planning | |
| on talking to maxima the way the Symaxx maxima | |
| interface (http://symaxx.sourceforge.net) does - write | |
| the proper instructions to a temp file and then invoke | |
| the command line maxima using the file as the input. | |
| They are using Perl/Tk, and I'm pretty sure that part | |
| of it doesn't depend on Tk. Probably not the best way | |
| to do it, but it's about the simplest and it's been | |
| shown to work. I confess to total ignorance here - | |
| what function does the signaling mechanism serve? | |

| That's essentially what I had intended to do - the | |
| MathML would only be for the purpose of displaying the | |
| formatted mathematics via the GTK widget. Maxima | |
| itself wouldn't ever get anything from the interface | |
| but it's own syntax, and that's all it would need to | |
| return - I shouldn't have to do anything to maxima | |
| itself at all. | |
| > You are just making more work | |

| > mathml and a translator out. | |
| Very true, but I figured that would be less work than | |
| writing my own GTK code from scratch to handle TeX | |
| output. Maybe it wouldn't be - that's a definite | |
| possibility if I find that a MathML <-> maxima perl | |
| script is too much work. Remember, though - the only | |
| real translation would be for a very small subset of | |
| the MathML standard. Fractions, exponentials, | |
| integrals, stuff like that - the rest of the maxima | |
| input/output would be in its original form throughout. | |

| Do you mean communicating between the frontend and | |
| maxima? The only direct communication would be when | |
| the frontend runs maxima on the temp file. Symaxx | |
| functions in this fashion, and I've never had a speed | |
| problem with it. I'm not sure what communication | |
| protocols I would need - perl can just run the maxima | |
| program with the temp file input - the frontend would | |
| use the perl scripts to translate the maxima output | |
| file into display ready content. Unless I'm missing | |
| something shouldn't be too much trouble for shorter | |
| expressions (that is an unexplored point, I grant you | |
| - I have to write the scripts before I can do speed | |
| trials. Still, since it is ascii text manipulation, I | |
| can't imagine it being that slow.) | |

| I don't know lisp (I would like to learn - that's | |
| another one of those "if I only had time" or rather | |
| "if only my school offered credit for it" things.) If | |
| that's how things shape up I'll give it a try. | |

| crazy :-) | |

| this beginner.) | |

| Hello | |
| Looking at my students, it is clear that they don't like the command | |
| line at all, so i find that an interface like mathematica for maxima is | |
| a good project. | |
| It must allow to use classical mathematical notations for input and | |
| output. | |
| Best regards. | |

| Hello | |
| I have maxima 5.5 beta 3 with a mandrake 7.1. When i launch xmaxima, i | |
| can enter and evaluate the expressions, but when i click on the items | |
| of any menu, it will do nothing. | |
| It's the same problem with the plots. The menus brings up, but they | |

| Any idea ? | |

| Dear friends of maxima, | |
| I can explain with better precision the | |
| feature I told you about a few days ago : | |
| 1. please launch fistly top to see the active processes | |
| 2. then launch xmaxima, then exit via the menu | |
| 3. if the behaviour is the same as on my Linux Mandrake 7.1 | |
| box, you'l quickly see saved-maxima using 98% of cpu time. | |
| 4. ad libitum, the cpu time being divided between the several | |
| saved-maxima processes... | |
| I use maxima 5.6 compiled with gcl 2.4.0. | |
| Best regards | |

| Using maxima 5.6. It is strange, but I use mandrake 7.2 at home and | |
| everything works fine. Here at work, I get exactly the same behaviour | |
| as you describe. I am using RH 6.2 here, with tk8.0. At home I use | |
| tk8.3. However I did try the tk demos here at work and all the | |
| menu/button demos worked just fine. | |
| I hope a solution is discovered. | |

| Greetings! Yes, apparently what's going on is that the xmaxima tcl is | |
| closing the socket to the saved_maxima process without successfully | |
| terminating it first. saved_maxima then loops forever on select of | |
| the file descriiptor, which being closed, returns a "bad file | |
| descriptor" error. Simplest fix would be to patch xmaxima, but maybe | |
| it would be more robust if maxima itself exits when its input stream | |
| is closed? | |
| Take care, | |

| Greetings, and thank you again for the wonderful work on | |
| gcl-2.4.0/maxima-5.6! | |
| It appears now with the compiled in inclusion of some of the gmp code | |
| into gcl, that subarchitecture dependencies are introduced into the | |
| resulting binaries. This complicates making x86 binaries to include | |
| in a distribution such as Debian. Of course, the difference in | |
| performance is well worth the extra effort. | |
| Here's my plan -- build each of the gmp x86 subarch options as | |
| separate shared libraries, install these under | |
| /usr/lib/{k6,k7,p6,...}, and let ld.so load the fastest one at | |
| runtime. The portion of the gcl build which actually runs raw_gcl | |
| will be invoked with an LD_LIBRARY_PATH choosing a generic shared | |
| lib. | |
| Is this going to work? | |
| Take care, | |

| Grabbed the 5.6 release and rebuilt with cmucl. Everything works but | |
| I did run into a problem. | |
| Some of the tests fail. However, if I delete the mstuff fasl file and | |
| recompile everything, the tests work just fine. I have no idea why | |
| this is. My guess is something that's compiled before mstuff | |
| influences how mstuff gets compiled, but only when that thing is | |
| compiled, but it has no effect if that fasl is LOAD'ed before | |
| compiling mstuff. | |
| Also, I think I found the problem with cmucl and compiling plot.lisp. | |
| The defstruct for polygon is wrapped inside an eval-when | |
| compile/eval. If I take that outside, and reinstate the make-polygon | |
| macro (after renaming the defstruct constructor from make-polygon to | |
| %make-polygon to prevent a collision), plots work. | |

| Somehow either you have moved the gcl from where you built it or removed | |

| such thing, since the cmpinclude.h is in gcl-2.4.0/o among other directories and that is in the gcc command line that is being passed. | |

| in the configure of gcl, I included | |
| (cd gmp ; ./configure --target=pentium) ;; | |
| I intended to include a line in the gcl/configure.in to make the | |
| configuration on any pentium, 686, pentiumpro, athlon etc use pentium | |
| which I think should work for almost all machines now adays. This | |
| would hurt performance a bit, but at least let the same binary work on | |
| all. However, the '[' ']' got stripped in the making of configure | |
| from configure.in and the test regexp i5-986* |pentium* | ... which | |
| would not match lots, and so the default configure is used for those | |
| machines. Ie a more machine specific one. So you could just fix the | |
| above in the configure. I am still unsure what the best target to use | |
| would be.. On the machine I was running on I found that the | |
| distributed shared gmp.so was actually compiled incorrectly for my | |
| architecture, and so gave a segfault on certain gcl operations. That | |
| is part of the reason I include the part of gmp we need, to make sure | |
| it is compiled correctly. Also I needed to include it to make some changes | |
| to functions to help the gc. | |
| case "${canonical}" in | |
| i[5-9]86* | pentium* | k6* | athlon*) | |
| (cd gmp ; ./configure --target=pentium) ;; | |
| *) | |
| (cd gmp ; ./configure) ;; | |

| with a nonzero | |
| plot.c: In function `L84': | |
| plot.c:9924: virtual memory exhausted | |
| cpp: output pipe has been closed | |
| Yes it would appear that gcl was not propagating correctly the failure | |
| to compile due to gcc running out of space. I have fixed this in | |
| unixport/init_gcl.lsp: On a more practical note, if you run out of space | |
| like that you can remove the -pipe from the gcc flag, and it should | |
| use temp files, which will take less swap space. | |

| Mathematica ability of inputing things like integrals | |
| "graphically" (for lack of a better term.) Sorry, I | |
| guess I don't know how to express it more clearly. Or | |
| maybe I'm not thinking about maxima the correct way. | |
| You really maybe should take a look/try at TeXmacs. | |
| http://www.texmacs.org/ | |
| It lets you type in math in graphical form, but normally maxima input | |
| is in maxima form, just the output is tex like form. It actually | |
| uses mactex.lisp (fateman's file). The interface was done by | |
| [email protected] | |
| It does not yet allow interrupts, but I think that is a solvable | |
| problem, just as I do in netmath. You just have to listen for a | |
| signal or listen on a second channel. Maxima can say accept a signal | |
| and then do something, like stop the computation. Under windows I | |
| have a hack winkill.exe which lets me get around the lack of signals. | |
| Also it needs something to associate to each part of the tex | |
| expression the maxima part which generated it. This should be | |
| simple, yet would let mousing a subexpression. | |
| This could be done on a second pass too: For example if | |
| the maxima side remembered the lisp form of the tex expression it | |
| sent, and then texmacs communicated back a certain string range | |
| of the tex expression, then mactex.lisp could make a second pass | |
| figuring out which subform caused the generation of the relevant | |
| region of the string. | |
| eg ((mplus) ((mexpt) $x ((mplus) $u $v))) ==> x^{u+v} | |
| so if TexMacs said to maxima we have boxed something that is a | |
| substring from 2 to 5, then it would be trivial for maxima to | |
| know it was ((mplus) $u $v). | |
| are actually rather low. I just like the illusion of | |
| doing something worthwhile. ;-) | |
| It is hard to know what is worth while till it is done. Sometimes a | |
| snazzy interface helps attract users, even if it is not as effective | |
| as a simple one. | |

| This is a fine solution as well. I just uploaded last week a package | |
| configured as a '486'. Question: how much does maxima use the gmp | |
| code? How significant is the tuning of this library on the typical | |
| overall performance of maxima? Because it also appears as though the | |
| shared lib approach will work. This wastes disk space (~ 300k in the | |
| included gmp sublib!) but provides a more optimal binary across | |
| subarchitectures, provides a seamless cpu upgrade path, as well as | |
| support for nfs mounting /usr across a LAN, etc. I really don't know | |
| how to evaluate the tradeoff. | |

| Yes this latter is especially important, AFAICT. You state that you | |
| replace a malloc with a tmp-alloc in one of the mpn files. Does this | |
| "help" gcl, or is it required to make it function correctly? Have you | |
| by any chance had the opportunity to request the gmp authors to | |
| consider including this change? Of course it would be cleaner if one | |
| could avoid duplicating the gmp code/source, but a safe correct | |
| functionality is of course the highest priority. | |
| Can you foresee any problems compiling against an installed gmp | |
| library version 2.0.2? | |

| One final unrelated question -- do you know of any other applications | |
| atop gcl? Right now, the maxima build includes a gcl sub-build as | |
| part of the process. I'm considering reworking this to make a gcl-dev | |
| package for Debian, and was wondering if there was any other code that | |
| could benefit. | |
| Take care, | |

| implementation in GCL. Basically it is so we can use the strategy | |
| for garbage collection. I will try to convince the gmp | |
| authors to make the change. Also I would like to use a relocatable space | |
| strategy for the bignums, but that will require some more minor changes | |
| to gmp. I think I have almost made them, but there is at least one | |
| that is illuding me. [ (si::SET-GMP-ALLOCATE-RELOCATABLE t) will switch | |
| to relocatable, but some random bugs will appear if you compute a lot!] | |
| The changes I am making are ones that could be included in the | |
| distribution. But I think for the present we are safer in having a | |
| copy of the gmp in gcl, especially since some users might not have gmp | |
| on their system, and the number of functions we need from gmp is not | |
| so huge. | |
| I think for something like the debian distribution, your doing the | |
| 486 distribution is a fine. If someone is doing a lot of computations | |
| involving bignums, he can recompile gcl/maxima himself for his machine. | |

| [email protected] reports problem with redhat 7.0: | |
| 1. Yesterday, I tried to install Maxima 5.6. It seems that there were no | |
| error messages during make (there were some warnings while making gcl | |
| 2.4.0), but many self-tests fail. Also, I get the same behaviour as | |
| reported recently in sci.math.symbolic: integrate(x,x); yields | |
| x^2*false^2/2, integrate(sin(x),x); produces division by zero. This is on | |
| I believe this is related to the buggy gcc version 2.96 released with | |
| redhat/cygnus. Basically it is badly broken on -O4 optimize and it is | |
| hard to see how they could have released it. I have made some patches | |
| to gcl's configure and to the compiler invocation code, to not use | |
| -O4 when this compiler version is there. Please | |
| I have patched the configure | |
| in gcl to detect that buggy version. Note that maxima is now compiled | |
| on -O4 by default, and the above configure patch and patch to the | |
| compiler invocation in gcl, will shut off -O4 for this compiler. | |
| Basically configure if it detects this compiler version should add | |
| a #define BROKEN_O4_OPT, and the broken_o4_opt feature gets added | |
| to the lisp, so that maxima will not get compiled with -O4. | |
| So you should take the latest cvs/gcl or gcl daily snapshot to get | |
| those changes if you are using redhat. I dont have a redhat system | |
| here myself, so if someone could please check this out. | |
| Thanks | |

| The best would be to have support for the standard unix signals. | |

| I would rather be in favour of another mechanism | |
| if this subexpression handling is really important, | |
| although it may take a few months before I will implement it. | |
| The idea would be that Maxima sends "labeled output" to TeXmacs: | |
| each subexpression which you might want to select is given a label. | |
| TeXmacs may send this label back when the expression is selected, | |
| so that Maxima can reindentify the subexpression. | |
| This mechanism has the great advantage of not complicating | |
| the conversion algorithms (TeXmacs does NOT use LaTeX as its | |
| intern format, so your LaTeX output is also being converted). | |
| Furthermore, one might consider some more fancy add-ons, | |
| like further expansion of the O() part of a power series if | |
| you double click on it. | |

| There are other (not as good) ways of dealing with | |
| large expressions like scrolling horizontally | |
| or forceably ripping the horizontal expression | |
| somehow (this is inevitable in some sense, because | |
| you can create single symbols that exceed a line | |
| in length. e.g. 1000!. | |
| ) | |
| There should be no problem in feeding labels to | |
| Texmacs to identify what has been selected | |
| functionally. If you want to point to a | |
| part of the expression in the Maxima system | |
| as opposed to constructing a new subexpression, | |
| you have to have pointers into the actual | |
| lisp. This could be done (for example) by | |
| hash-coding all subexpressions, giving them | |
| tags, and telling Texmacs what those tags are. | |
| However, not everything that you display | |
| exists in the lisp. | |
| For example a/b is internally something like | |
| (* a (expt b -1)) so there is no division. | |
| a+b-c is (+ a b (* -1 c)) so there is | |
| no "-", just a constant. | |
| There is a program called FORMAT which is | |
| used to make such changes prior to display. | |
| If you pick things out of the result of | |
| FORMAT, that is merely a temporary data object, | |
| and not permanently stored. There are | |
| commands PART and INPART in Maxima. INPART | |
| works on the unformatted version, PART on | |
| the formatted version. | |
| If you do not want pointers back into the | |
| existing lisp, but are happy re-creating | |
| subexpressions, then there are neater solutions. | |
| I'm not sure what is required though. | |

| The idea would be that Maxima sends "labeled output" to TeXmacs: | |
| each subexpression which you might want to select is given a label. | |
| TeXmacs may send this label back when the expression is selected, | |
| The problem I see with labeling input is one has no idea what the user | |

| a tree what character index you were at in the input string -- or else | |
| perhaps better have a subsequent parse pass compute the range in case | |
| the user moused some box ... In this latter method there is no extra | |
| storage associated either on the maxima or texmacs side, just a cost | |

| I once constructed something like texmacs where I did the display myself, | |

| Once again, the problem is that there is not just one parsing algorithm | |
| involved : you have at least three parsing algorithms followed by several | |
| tree rewriting passes in order to upgrade to the current TeXmacs version. | |
| It would be very difficult in this stage to associate string locations to | |
| each cursor position. | |
| On the other hand, what you say is not necessarily a problem and | |
| we may inspire ourselves by the way XML handles portions of a document. | |
| In order to specify an entry of a matrix, we might use | |
| something like [Label matrix]/[x,y-position], for a range of terms | |
| [Label polynomial]/[start position]-[end position]. | |

| Indeed, this is true. I tried to compile gcl-2.4.0 & maxima-5.6 on | |
| my AltLinux Spring 2001(this is the Russian edition of Mandrake 7.2). | |
| This distribution has gcc-2.96. So, I had problem with rtest(3,5,6,13,14).mac's. | |

| There were no problems with tests and with things like integrate(x,x) as well, after this. | |

| Maxima computes a result. a/b. Internally this is | |
| ((mtimes simp) $a ((mexpt simp) $b -1)). Let's abbreviate this | |
| to | |
| (* a (^ b -1)) | |
| The formatting program changes this to | |
| (quotient a b) and the display program (DISPLA) prints it | |
| as | |
| A | |
| --- | |
| B | |
| I do not know much about Texmacs, but perhaps one could work at | |
| this... | |
| after running through format, and then through mactex, we get | |
| something like | |
| {a \over b} or maybe \frac... [I don't really care] | |
| The new version would be | |
| (\tag 1 {\tag 2 {\frac {\tag 3 a} {\tag 4 b}}}} | |
| where internal to maxima we have a hash table that has, for every | |
| expression sent to the front end, an index into the formatted (not | |
| the internal) form. That is, hashing | |
| (1 2 3) or maybe just 3 | |
| would be a pointer to the location of the "a" in expression | |
| 1. | |
| (1 2) or just 2 would be the whole fraction. | |
| calling the simplifier on the formatted form produces a simplified | |
| internal form. It is not the same tree as we started with, but should | |
| be pretty close. | |
| Anyway, selecting terms 20 to 24 of a 100 term polynomials would | |
| (I guess) require communicating 2 or more index sets to the back end, | |
| where the pieces would be assembled. | |
| On the Texmacs side, you would have to strip off the tags and save | |
| the index numbers, and support pointing/selection. This is now | |
| supported by commercial macsyma and mathematica, as well as the | |
| very nice interactive systems http://www.livemath.com/ | |
| by Allan Bonadio. | |
| ( In fact, a nice solution to the user interface | |
| but not free) would be to take Bonadio's | |
| system and attach Maxima to it. You should in any case | |
| take a long look at Bonadio's design!) | |

| On the TeXmacs side, I would have a typesetting construct "tag", | |
| which takes two arguments : an invisible label, and the tagged expression. | |
| Whenever you select an expression, I might return all corresponding tag | |
| information. For other purposes, the tags might be stripped. | |

| I'll take a look when I have time. Anyway, I do have lots of ideas waiting | |
| to be implemented, so time is more a problem as ideas... | |
| What is interesting about TeXmacs, is that many computer algebra systems | |
| have already been linked (up to 8 at this moment), so the comments by | |
| different people might lead to a free greatest-common-useful interface. | |
| Don't forget that TeXmacs il *also* an extensible typesetting system : | |
| you may directly incorporate your computations in TeXmacs articles. | |
| Finally, TeXmacs will become a WEB-authoring tool, as soon as the | |
| converters with Html/Mathml/Xml are ready... | |

| Kachian's algorithm is an algorithm that produces a numerical approximation | |
| to an optimal solution to an LP. The LP would have to be expressed with | |
| numerical coefficients. | |
| I'm not aware of any general purpose algorithm for solving an LP with | |
| symbolic coefficients. However, if the coefficients are rational numbers, | |
| then it is possible to get an exact rational answer using the simplex | |
| algorithm. This is implemented for example in Maple V. | |
| There are also "sensitivity analysis" techniques for analyzing the optimal | |
| solution to an LP to determine for what range of coefficients the solution | |
| would remain optimal. It's possible that such techniques would be useful | |
| here. | |

| Anyone know if anyone has gotten Maxima to run on an OpenVMS Alpha platform? | |
| I know that there used to be a OpenVMS VAX version of Macsyma so I'm | |
| wondering if anyone has worked with Maxima. | |
| (I loved Macsyma, used to bring many a university VAX to a crawl with large | |
| plots. So I was happy to see Maxima :}) | |
| If not, I think I could probably give a shot at porting it, that is, if I | |
| can find a Lisp system for OpenVMS :} | |
| Thanks for the great work on Maxima, I love it. | |

| Greetings! I know of no such port, but would encourage your efforts | |
| here. Unless you intend to use an existing lisp on this platform, the | |
| real job will be in porting gcl, after which compiling maxima should | |
| be straightforward. In principle, one need only supply a <arch>.defs | |
| and <arch>.h file in gcl-2.4.0/h/, and make sure that configure | |
| selects this arch. In practice, I've found getting a correct set of | |
| definitions in these files a bit challenging, and really requiring more | |
| time than I have. If you do succeed, please post your changes here -- | |
| I'd wager they'd be close to the modifications necessary to get a | |
| compile on a Debian Linux Alpha. | |
| Take care, | |

| Is it possible to mix Lisp and Maxima code in the same file and | |
| have Maxima load, translate, and compile the file? I haven't been | |
| able to do this | |
| Here are simple examples with one lisp form and one maxima form, but | |
| there can of course be many such forms in the file: | |
| The following is lisp file can be loaded with load("foo.lisp"); | |
| =======foo.lisp================= | |
| (in-package "MAXIMA") | |
| (defun $joe (x) (+ x 1)) | |
| #$f(n):=block([ans:0], | |
| for j:1 thru n do ans:ans+x^j, | |
| ans)$ | |
| ==============end foo.lisp======= | |
| and you will be able to do | |
| (C1) load("foo.lisp")$ | |
| (C2) joe(5); | |
| (D2) 6 | |
| (C3) f(3); | |
| (D3) x^3+x^2+x | |
| The above file however will not compile, and the maxima function | |
| f still acts as a regular maxima function. In order to translate | |
| it to lisp so that the compiler can act on it do the following: | |
| (C1) load("help.lisp"); /* see this file below */ | |
| (C2) :lisp (compile-file "foo.lisp") | |
| (C2) load("foo.o"); | |
| =======foo1.lisp================= | |
| (in-package "MAXIMA") | |
| (defun $joe (x) (+ x 1)) | |
| (tr #$$f(n):=block([ans:0], | |
| for j:1 thru n do ans:ans+x^j, | |
| ans)$ ) | |
| ========end foo1.lisp============ | |
| The helper macro 'tr' is defined in help.lisp (note | |
| we also have to define send, since it is used by the double $$ | |
| sharp reader macro we use in the above. We will add that | |
| function to maxima in the next release. | |
| =========help.lisp======================================== | |
| (in-package "MAXIMA") | |
| ;; some patches to let the above mixed lisp and maxima work ok. | |
| (defun send (a b) (if (eql b :tyi) (tyi a) (error "unknown send"))) | |
| (defmacro tr (u) | |
| (and (consp u) (eq (car u) 'quote) | |
| (BIND-TRANSL-STATE (translate-macexpr-toplevel (second u))))) | |
| =========================================================== | |
| Please note that the translation from maxima to lisp is not guaranteed | |
| to keep all the 'features' of the maxima language. If you are having | |
| a problem with speed of your maxima level code, certainly you can | |
| try translating and compiling it. You can also write critical portions | |
| of your code directly in lisp which will almost certainly produce faster | |
| code. | |

| Greetings! Has anyone fixed the xmaxima shutdown problem discussed | |
| here a while ago? Just as a reminder, shutting down xmaxima from the | |
| menus leaves a saved_maxima process taking up 100% cpu. | |

| I am putting a fix in the cvs directory | |
| http://cvs.math.utexas.edu/cgi-bin/cvsweb.cgi?cvsroot=maxima | |
| See bin/xmaxima | |
| If you get a new xmaxima then it should work correctly if either the | |
| window manager shuts it down with a 'delete' or if you use either of | |
| the 'exit' menus on xmaxima. Note I believe the MS windows version was | |
| correct, and this got broken in making the windows version ... | |
| william | |
| ps: However if you just destroy the xmaxima or kill it with a | |
| signal, then the maxima process is still left running and needs to be killed | |
| with a signal. I should fix that too .. but later. | |

| I need to use extended euclidean algorithm to solve some diophantine | |
| equations. I'd like to use free software for this, but unfortunately I | |
| can't find a corresponding routine in either Maxima or Pari/GP. | |
| In maple there is the function gcdex, when given polynomials a(x) and | |
| b(x), it finds c and d such that | |
| c*a(x) + d*b(x) = 1 | |
| For example, if a(x)=x^16+1 and b(x)=x^16-1, then c=1/2 and d=-1/2 because | |
| 16 16 | |
| x + 1 x - 1 | |
| ------- - ------- = 1 | |
| 2 2 | |
| Have I missed something, or can't Maxima (nor Pari!) really do this? | |
| Another thing that bugs my slightly is that Maxima uses only 80 columns to | |
| display even if I'd have much more. | |

| Oddly enough, the user level of Maxima seems not to | |
| have an implementation of the extended Euclidean algorithm. | |
| (Macsyma has one: extgcd). | |
| It takes about 6 lines of code to write it. | |
| What makes it odd is that Maxima uses this code internally | |
| in many places. It has to be set up right, with a main variable, | |
| which may make it tricky to do in some robust user-friendly way. | |
| To change the line length to, say, 100, type linel:100$ | |

| In the "preferences" menu there is a mention of | |
| "proportional fixed font" which I assume should be | |
| "fixed font" | |
| If you type, for example, describe("gcd") there are several items | |
| listed and you are invited to type one or more of their | |
| numbers. | |
| It seems you must terminate the line with a ";" or | |
| nothing happens. But the ";" is left over and becomes | |
| a null command line after the describe() is finished. | |

| Hi, | |
| I'm working on some routines for optimization using Maxima (e.g, | |
| second-order Newton method, Levenberg-Marquardt), and I've run into a | |
| problem with routines related to matrix manipulation. For example, when one | |
| solves a matrix equation A.x = b by using x:invert(A).b, x is a list of | |
| lists. So, when this is done in an iterative loop, the problem compounds | |
| itself so that on the next iteration one gets a list of list of lists, etc. | |
| Another example is when one forms a row vector by doing something like | |
| v:transpose([1,2,3]) - this also gives a list of lists. Is there any way of | |
| controlling or avoiding this behavior in Maxima? I am not yet sufficiently | |
| familiar with Maxima programming to see a way out of this. | |
| Many thanks for any advice, etc., on this. | |
| Sincerely, | |
| David Holmgren | |

| As an example, take a:transpose([1,2,3]) which is a column vector. | |
| When you say a[1], Maxima returns [1] and not 1, which is more desirable in | |
| some situations (eg., when you compute x+dx, where x and dx are two | |
| vectors). Effectively, a seems to be [[1],[2],[3]] rather than the [1,2,3] | |
| I expected (with everything transposed to make column vectors of course). I | |
| can certainly apply part(a,1) repeatedly, but it would be nice to not have | |
| to do this. | |

| I certainly appreciate that, but again, if a vector is updated in a | |
| loop, you can end up with several dimensions. Generally, I've found that | |
| Maxima crashes before proceeding too far along these lines! | |

| There are a bunch of flags, but none that looks | |

| Question About Matrices: | |
| 1) A matrix is ALWAYS represented internally as a list of rows, each row | |
| of which is a maxima list. | |
| If M is a matrix then M[i] is the ith row, and hence a list. Similarly | |
| M[i,j] is an entry the i,j entry with 1,1 top left corner entry. | |
| 2) If you do transpose(x) and x is a matrix or list the result is always a matrix. | |
| The case of x a list is a convenient way of building a column matrix | |
| 3) To turn a matrix into a simple list of all the entries, with first row then | |
| second row etc.. you could do: | |
| ListMatrixEntries(m):=block([ans:[]], | |
| for v in m do ans:append(ans,v), | |
| ans); | |
| ListMatrixEntries(matrix([a,b],[c,d]))==>[a,b,c,d] | |
| ListMatrixEntries(transpose([a,b,c])) ==> [a,b,c] | |
| In lisp to define the same thing you could do | |
| (defun $LIST_MATRIX_ENTRIES (m) | |
| (or ($matrixp m) (error "not a matrix")) | |
| (cons '(mlist) (sloop for v in (cdr m) append (cdr v)))) | |
| I will add this function to maxima | |
| since I know from experience it is useful. I call it | |
| $LIST_MATRIX_ENTRIES to be compatible with the usual conventions in maxima. | |
| Note | |
| (defun |$ListMatrixEntries| (m) ...) would have defined the one with the mixed | |
| case name. | |

| In maple there is the function gcdex, when given polynomials a(x) and | |
| b(x), it finds c and d such that | |
| c*a(x) + d*b(x) = 1 | |
| I have added a little file gcdex.mc in the share/gcdex.mc | |
| distribution which does what you want [it is below], ie the euclidean | |
| algorithm for univariate polynomials which can then demonstrate that | |
| this is a principal ideal domain, by finding gcd of f and g in the | |
| ideal generated by f and g. | |
| line width: | |
| As richard said, the maxima variable linel, or the lisp variable linel | |
| control the line width of the terminal display. linel:80 being the default. | |
| If you can determine your linewidth automatically somehow then you could | |
| use the lisp (setq linel (si::getenv "COLUMNS") ) or some such thing in the | |
| init.lsp loaded from your directory where you start maxima. xmaxima is supposed | |
| to figure out the linewidth, since it is actually handling the window. | |
| =============begin gcdex.mc========== | |

| ideal domain, and the ideal generated by (f,g) is indeed generated | |
| by the gcd of f and g. | |
| mytest(f,g):=block([ans:gcdex(f,g)], | |
| [ratsimp(ans.[f,g,-1]), | |
| remainder(f,ans[3]), | |

| do that. It should be easy to add a new Lisp function (written in C) to | |
| return the current line width. Would you like a patch if I make one (when | |

| In the diophantine equation gcdex example, I think there | |
| are a couple of ways of improving it. | |
| Thesize of the program can be reduced by using multiple assignment | |
| syntax (a secret? in macsyma). | |
| [a,b,c]:[1,2,3] assigns a:1, b:2, c:3. | |
| [quo,rem]: divide(p,q,x) sets the quotient and remainder [main var x] | |
| I usually set the original inputs into rat form, making | |
| it unnecessary to call ratsimp along the way. It should | |
| be possible to copy the gcdex out of Knuth vol 1, but | |
| I'm away from my library right now. | |
| It should be possible to do the computation even if the | |
| two inputs are not univariate, by choosing to do the | |
| computations in the quotient field of the other variables. | |
| thus the call could be gcdex(u,v,x), where x is also used | |
| in the call to divide. | |
| The various options here are probably what made people | |
| nervous about including the program as a user command. | |
| The commercial Macsyma (or formerly commercial?) | |
| has this program: | |
| XTGCD(poly_or_integer, poly_or_integer) | |
| [ALGFUNCS package] Computes the extended Euclidean algorithm for the | |
| integers and/or univariate polynomials with integer coefficients. | |
| Returns the list [p(x), a(x), b(x)] where q(x) and r(x) are the | |
| arguments to EXTGCD, p(x) is their g.c.d., and a(x) and b(x) satisfy | |
| Bezout's identity | |
| p(x) = a(x)*q(x) + b(x)*r(x) . | |
| Do EXAMPLE(EXTGCD); for an executable example. | |
| See also EXTGCD_INTEGER. | |
| The EXTGCD code follows the design in | |
| J.H. Davenport, Y. Siret, and E. Tournier | |
| Computer Algebra: Systems and algorithms for algebraic computation | |
| Academic Press (1988), pp. 213-214 | |
| even down to the names used. | |

| [David Holmgren] Many thanks! I suspected that one would have to | |
| do something like your ListMatrixEntries. | |

| Package: maxima | |
| Version: 5.6-6 | |
| Severity: normal | |
| The result of the "sum" command displays the summation symbol | |
| with the symbols in the wrong places: | |
| Actual maxima output: | |
| (C2) sum(n^2,n,1,n); | |
| n | |
| ==== | |
| \2 | |
| (D2) >n | |
| / | |
| ==== | |
| n = 1 | |
| Output should be: | |
| (C2) sum(n^2,n,1,n); | |
| n | |
| ==== | |
| \ 2 | |
| (D2) > n | |
| / | |
| ==== | |
| n = 1 | |
| I have a windows version of maxima 5.5 that displays correctly so the | |
| difference may have occurred between maxima 5.5 and maxima 5.6. | |

| in lisp, | |
| (defun $LIST_MATRIX_ENTRIES (m)... (apply #'append (cdr v)) instead | |
| of sloop... | |
| I put the version using 'sloop' in the sources because I think it is | |
| more readable, and I KNOW it is efficient in every lisp, not creating | |
| any more cons's than absolutely necessary. For example if you do | |
| 5000 iterations of doing list_matrix_entries of a 7 7 matrix. | |
| Cons's Seconds Method | |

| 320,000 1.65 apply '$append | |
| 3,600,000 42.0 apply (append, substinpart("[",M,0))$ | |
| I guess I am very sensitive to storage use and timings .. and I probably | |
| go a little overboard on making things efficient. But I do think the sloop | |
| (sloop for row in (cdr matrix) append (cdr row)) | |
| "for each row in matrix append the row" | |
| is pretty readable. Of course I wrote the sloop macro, so thats probably | |
| why I think it is readable, but it is also why I am sure it is efficient. | |
| The lisp version you suggest: | |
| (defun $LIST_MATRIX_ENTRIES1 (m) | |
| (or ($matrixp m) (error "not a matrix")) | |
| (apply #'append (cdr m))) | |
| needs to use '$append since the rows are maxima lists not lisp lists. | |
| Note the timings were done on a slow notebook (166Mhz) here in St Petersburg | |
| russia, and so may appear high. Functions were compiled, and I used gcl's | |
| gc monitor. | |
| ========================== | |
| III. | |
| You might prefer this version of gcdex, though it takes | |
| an additional argument, the main variable..., it does | |
| not require that expressions be univariate. | |
| gcdex1(m,n,x):= | |
| Thank you yes we should handle the case where coefficients are in some rational | |
| function field. | |
| Normally when we speak about gcd of elements in k[x,y] we mean in the | |
| polynomial ring in two variables, where of course ideals cannot be | |
| generated by one element .. their gcd. | |
| x k[x,y] + y k[x,y] != 1 k[x,y] | |
| But if we look at the field of fractions k(y) and then adjoin x, then | |
| of course that ring k(y)[x] is a Principal ideal domain (indeed a euclidean | |
| domain), and we can use the euclidean algorithm and produce elements which | |
| will be fractions in y but polynomials in x. I have modified share/gcdex.mc | |
| to allow an optional argument specifying a main variable. Just remember the | |
| gcd is not the usual multivariate gcd! | |
| gcdex(x*(y+1),y^2-1,x); | |
| 1 | |
| (D1) [0, ------, 1] | |
| 2 | |
| y - 1 | |
| saying the 'gcd' is 1, since that is what it is in k(y)[x], | |
| however it would be of course y+1 if we were just thinking in k[x,y]. | |
| Note that I did not actually get the code you sent to work correctly. | |
| I added SUBSCRMAP:true to the binds, so that the list assignments would be ok, | |
| but still it gave incorrect answers: | |
| (C17) gcdex1(x^3+2,x^3+1,x); | |
| 3 3 3 | |
| (D17)/R/ [x + 1, x + 1, x + 1] | |
| but anyway I am sure knuth's algorithm is correct and there is just a typo somewhere.. | |
| but I dont have the book with me and so can't verify it, and once I have one | |
| working it is hard to go back and trouble shoot another! | |

| Good *ing, | |
| This is a suggestion for William (and/or anyone interested in | |
| developing it... maybe I should try to do it myself, but ;-) | |
| better if someone with more experience tries to). | |
| I think Maxima should have an easy method for plotting para- | |
| metric curves and surfaces..., like | |
| parametricplot2d([3*cosh(t),3*sinh(t)],[t,-2,2]); | |
| to plot a ---guess it--- hyperbola, and | |
| parametricplot3d([cos(theta)*cosh(t), | |
| sin(theta)*sinh(t),t],[t,-3,3], | |
| [theta,-%PI,%PI]); | |
| for a catenoid (?). | |
| I know it could be done using the gnuplot interface, etc... but I | |
| think a straightforward command for omplot (great!) would be best. | |
| Thanks in advance, | |
| Pedro. | |

| I think Maxima should have an easy method for plotting para- | |
| metric curves and surfaces..., like | |
| parametricplot2d([3*cosh(t),3*sinh(t)],[t,-2,2]); | |
| I have added a 2d parametric plot. I believe I added the 3d one a couple | |
| of years ago, and I am not sure why I did not do a 2d one.. | |
| For plot3d for example doing a moebius band: | |
| plot3d([cos(x)*(3+y*cos(x/2)), | |
| sin(x)*(3+y*cos(x/2)),y*sin(x/2)], | |
| [x,-%pi,%pi],[y,-1,1],['grid,50,15]); | |
| thus the first argument is a list of 3 functions, in the parametric case. | |
| For plot2d, since the argument could already be a list of functions (meaning | |
| plot them all simultaneously on the same window), I added parametric expressions: | |
| things like | |
| [parametric,cos(t),sin(t),[t,-5,5]] | |
| which would mean the unit circle. | |
| (C1) plot2d([parametric,cos(t),sin(t),[t,-%pi*2,%pi*2]]); | |
| (C2) plot2d([parametric,cos(t),sin(t),[t,-%pi*2,%pi*2], | |
| [nticks,8]]); | |
| (C3) plot2d([x^3+2,[parametric,cos(t),sin(t),[t,-5,5]]], | |
| [x,-3,3]); | |
| - Function: PLOT2D (expr,range,...,options,..) | |
| - Function: PLOT2D ([expr1,expr2,..,exprn],xrange,...,options,..) | |
| - Function: PLOT2D (parametric_expr) | |
| - Function: PLOT2D ([..,expr,..,parametric_expr,..],xrange,...,options) | |
| are the possibilities, so you can plot several parametric expressions. | |
| william | |
| [these things are in the cvs, you need | |
| src/plot.lisp src/max_ext.lisp info/Plotting.texi | |
| and I also had to change the gcl function info mechanism slightly (1 character | |
| change) to handle the 'describe' of multiple line info entries like the above.. see | |

| Dear Maxima experts, | |
| I agreee that the possibility od parametric plots is a good idea, but the | |
| third example | |
| > ... | |
| > (C3) plot2d([x^3+2,[parametric,cos(t),sin(t),[t,-5,5]]], | |
| > [x,-3,3]); | |
| > ... | |
| does not give any result with the option ['plot_format, GNUPLOT] and the | |
| data file "maxout.gnuplot" can be plotted via gnuplot after some changes. | |
| It will probably need some changes in "mgnuplot" file, I guess. Does | |
| anybody have an idea, how to change this file, please? | |
| Thanks for any hints | |
| Yours faithfully | |

| Hi, | |
| I'm running a big messy job, and run out of memory quickly. (Allocate | |
| 'cons really-big-number) doesn't help, because there just aren't enough | |
| pages to go 'round. I've tried setting *ignore-maximum-pages* to true, | |
| but that doen't seem to produce any effect. (Room) produces the | |
| following output at the beginning of a job: | |
| [tomlinso@desktop gcl-2.4.0]$ maxima | |
| GCL (GNU Common Lisp) Version(2.4.0) Wed May 9 12:02:00 CDT 2001 | |
| Licensed under GNU Library General Public License | |
| Contains Enhancements by W. Schelter | |
| Maxima 5.6 Wed May 9 12:01:49 CDT 2001 (with enhancements by W. Schelter). | |

| 378 pages for cells | |
| 556 total pages | |
| 30069 pages available | |
| 2143 pages in heap but not gc'd + pages needed for gc marking | |
| 32768 maximum pages | |
| MAXIMA>> | |
| That 32768 maximum pages seems to work out to about 128M, and I may | |
| well need four times that. I'm running this on a machine with 512M of | |
| ram and tons of swap space, and buying more ram isn't out of the | |
| question, so it makes sense to have a really big maximum pages. | |
| Is there an argument on the command line when I run gcl, or is there | |
| something I can edit in the config or makefile, which will give me some | |
| extra room? | |
| Thanks, | |

| extra room? | |
| To enable a larger page table in gcl you must configure it at compile time: | |
| cd gcl | |
| ./configure '--enable-maxpage=128*1024' | |
| make | |
| and then remove maxima/src/saved_maxima and remake in the maxima directory. | |
| The default should probably be bigger now that memory is so cheap. | |
| Note from the ./configure --help: | |
| --enable-maxpage=XXXX will compile in a page table of size XXX (eg '--enable-maxpage=64*1024' would give 64K pages allowing 256 MB if pages are 4K each) | |

| 1. Maxima's reset function is broken: (Maxima = Maxima 5.4 for NT or | |

| 2. For a rational x, the relative difference between x and float(x) is of | |
| the order 10^-8; Maxima's | |
| floats are (?) are type double-float, so the expected relative difference | |
| is about 10^-16. | |
| For example: | |
| (C1) x : 12345678912345678789 / 23456789123456789$ | |
| (C2) float(float(x) / bfloat(x) - 1); | |

| (D2) 5.669861827984831E-8 | |
| 3. There is documentation on the Maxima room function, yet it must be called as ?room() | |
| instead: | |
| (C4) room(); | |
| (D4) room() | |
| (C5) ?room(); | |
| 210/210 72.9% CONS BIGNUM RATIO COMPLEX STRUCTURE | |
| . | |
| . | |
| . | |
| 4. The Maxima version of apropos is documented, but seems to be missing. This | |
| works for me: | |
| (defun $apropos ( s ) | |
| (cons '(mlist) (apropos-list s "MAXIMA") | |
| ) | |
| 5. The Macsyma Inc function facsum was handy for putting expressions in to a readable | |
| form; unfortunately, facsum is missing from Maxima. At first I thought I could use | |
| factorout instead. The following does what I wanted: | |
| (C8) factorout(a*z + b*z + 1,a,b); | |
| (D8) (b+a)*z+1 | |
| But the following doesn't: | |
| (C13) factorout(s * 'diff(z,s) + z * 'diff(z,s) + 1,z,s); | |
| (D13) z*'DIFF(z,s,1)+s*'DIFF(z,s,1)+1 | |
| With the facsum function, we would get | |
| (c1) facsum(s * 'diff(z,s) + z * 'diff(z,s) + 1, 'diff(z,s)); | |
| (d1) (s + z) * 'diff(z,s) + 1 | |
| If anybody has a facsum function they can legally share, let me know. (The Macsyma | |
| documentation says it was written by RL Brenner and is in the facexp package.) | |
| 6. Is the Maxima Poisson package broken? | |
| (C1) intopois(cos(x) + 1); | |
| Illegal arg to POISSIMP: | |
| x | |
| -- an error. Quitting. To debug this try DEBUGMODE(TRUE);) | |
| 7. The Maxima FFT package is missing files or is broken. Anybody have one? | |

| Please forgive the newbie question. As I'm reading | |
| about GCL, is it correct that the maxima code is first | |
| translated to C code, and then compiled by gcc? Sorry | |
| if this should be obvious but I'm not completely clear | |
| on exactly how the compile process works. | |

| This looks like a bug in something that changevar calls. Consider | |
| the following: | |
| (C2) expr1:sqrt(a^2+sqrt(b^2+c/x)); | |
| c 2 2 | |
| (D2) SQRT(SQRT(- + b ) + a ) | |
| x | |
| (C3) assume(a>0,b>0,c>0,x>0,y>0,y>a); | |
| (D3) [a > 0, b > 0, c > 0, x > 0, y > 0, y > a] | |
| (C4) int1:'integrate(expr1,x); | |
| / | |
| [ c 2 2 | |
| (D4) I SQRT(SQRT(- + b ) + a ) dx | |
| ] x | |
| / | |
| (C5) change1:y=expr1; | |
| c 2 2 | |
| (D5) y = SQRT(SQRT(- + b ) + a ) | |
| x | |
| (C6) changevar(int1,change1,y,x); | |
| / | |
| [ c 2 2 | |
| (D6) I SQRT(SQRT(- + b ) + a ) dx | |
| ] x | |
| / | |
| Maxima can't do that but it can do: | |
| (C7) int2:scanmap(factor,changevar(int1,change1^2,y,x)); | |
| 2 2 | |
| Is a - y positive, negative, or zero? | |
| negative; | |
| / 2 2 | |
| [ y (y - a) (y + a) SQRT(2 a - y ) | |
| (D7) - 4 c I --------------------------------- dy | |
| ] 2 2 2 2 2 2 | |
| / (y - b - a ) (y + b - a ) | |
| The sqrt term is incorrect. It should be y. Maxima should have known | |
| that y^2 > a^2 from the assumptions but it definitely knows because | |
| I told it so. It ignored all that, assumed a^2 > y^2, and got the | |
| wrong answer. | |
| Perhaps the problem is related to this: | |
| (C8) change2:solve(change1^2,x)[1]; | |
| 2 2 | |
| Is a - y positive, negative, or zero? | |
| negative; | |
| c | |
| (D8) x = ---------------------- | |
| 4 2 2 2 4 | |
| y - 2 a y - b + a | |
| (C9) frob:subst(change2,expr1); | |
| 4 2 2 4 2 | |
| (D9) SQRT(SQRT(y - 2 a y + a ) + a ) | |
| Obviously, the inner sqrt is the issue. Note also, | |
| (C10) scanmap(factor,frob); | |
| 2 | |
| (D10) SQRT((y - a) (y + a) + a ) | |
| (C11) scanmap(factor,frob,bottomup); | |

| The maxima code is lisp, mostly. Some pieces are | |
| in the "macsyma language" and some may be in C or even | |
| assembler. | |
| There are many implementations | |
| of lisp. Some of them just execute the lisp in | |
| an interpretive fashion. Some compile lisp into assembler | |
| or binary code. Some of them translate lisp into C | |
| and then compile it. | |
| Maxima has been compiled on several lisps with different | |
| strategies. For example the Allegro Common Lisp version | |
| compiles from lisp into assembler. GCL uses C. There | |
| is nothing inherent in Maxima that requires it to ever | |
| be translated to C. It is just GCL's implementation | |
| strategy. The nice thing about it is that there are | |
| so many systems with C compilers, that it is a fairly | |
| general approach to portability. | |
| If you want to learn how to compile lisp, there are various | |
| places to look. A good one is Peter Norvig's Paradigms | |
| of AI programming. (It includes considerable amounts of | |
| other material also). | |

| Hi; | |
| I realize this is an unreasonable question. But what are mailing lists | |
| for? :-) | |
| I want to put together a FreeBSD port for maxima (analogous to an srpm | |
| for Linux folks.) Unfortunately release 5.6 does not work for me, | |
| while the CVS current does. Basically I need a known good snapshot or | |
| release to work against. Are there plans for such a snapshot/release | |
| in the near future? | |
| Of course I can always tar up the tree I just checked out (or use cvs | |
| export), but I'd rather not distribute a "rogue" version. | |
| All the best, | |
| David | |

| Hello, | |
| I think the function 'FORMAT' does what you tried with FACSUM. | |
| I tried FORMAT(s * 'diff(z,s) + z * 'diff(z,s) + 1, %poly('diff(z,s))) | |
| and got (z+s)*'diff(z,s,1)+1. | |
| The function comes in a package, which can be downloaded here: | |
| http://math.nist.gov/~BMiller/computer-algebra/ | |
| (Installation does not work the way it should on my machine, I had to | |
| 'compile_file' the format.lisp and coeflist.lisp files by hand and | |
| 'loadfile' the resulting .o files before using FORMAT. | |
| The package also provides its own Poisson function, as far as I know. | |
| Regards | |
| Markus | |

| Are there any prescriptions about using upper and lower case in mazima commands and variables names | |
| o is maxima completely case insensitive? | |

| Hi, | |
| I wish we could have a port of Maxima for Darwin, Apple's new OS. | |
| First I attempted to build GCL, but I couldn't so far and nobody was capable | |
| yet. | |
| To start with, I'd be glad with a command-line tool. So, I'm wondering how | |
| to do that. | |
| i)Is it possible to use another compiler? | |
| ii)Is there a workaround? Like transform lisp files in C files --- that's | |
| what gcl does isn't it? | |
| If you have any idea, I'd really appreciate any kind of help or hint. | |
| Thanks a lot, | |
| Lizardo. | |

| I am trying to exploit maxima to check some algebric calculations of mine; | |
| replacement of factors with others is something i am not able to get: | |
| Here is an example, in which chi*om12 should be changed into omega12, when | |
| the expressions are elements of a matrix, as in the batch file here enclosed. | |
| You can see that replacemnt in gradFF matrix elements has not had effect, | |
| i.e.: | |
| (C49) gradFF[1,1]; | |
| (D49) 2 v (t3 v + t2 v + j2 v - chi om12 t1) | |
| + 4 v (t3 v - t1 v - J1 v + chi om23 t2) | |
| + 2 v (t2 v - t1 v - (j2 + J1) v + chi om13 t3) | |
| By the way, gradFF is a vector, but it seemed that using a second (fixed) | |
| index to print out its elements gave no trouble, rather it allowed to hide | |
| the square brackets on the borders. | |
| I have checked that replacement can be performed in simpler expressions, | |
| so it is possible that my troubles are due to the way my matrix has been | |
| built up. | |
| thank you for your help | |

| Greetings: | |
| I like the OpenMath plotter that now bundled with maxima. Two | |
| questions for the people here who know it better than I: | |
| 1. Is there any documentation for the input file format? | |
| 2. Is it possible to have 3d plots with axes labeled and having tick | |
| marks? | |

| First, try using ratsubst instead of subst: | |
| (C5) subst(omega23, chi * om23, chi^2 * om23^2 + 43); | |
| (D5) chi^2*om23^2+43 | |
| (C6) ratsubst(omega23, chi * om23, chi^2 * om23^2 + 43); | |
| (D6) omega23^2+43 | |
| If this doesn't work, you can instead try something like | |
| subst(omega23 / chi, om23, ...) | |

| P.S. Many thanks for the folks who helped me with Poisson and helped me | |
| find the format package the other week; format has worked well for me and it even | |
| contains an enhanced Poisson package. Finally, | |
| (setq machine-mantissa-precision (float-digits 1.0d0)) works for me. | |

| The mmod function in trigi.lisp is to blame for the problem with sin(n %pi | |
| / 2) with | |
| n declared an integer. Changing MMOD to | |
| (defun MMOD (x y) | |
| (cond ((and ($ratnump x) ($ratnump y)) | |
| (let | |
| ((d (lcm ($denom x) ($denom y)))) | |
| (setq x (mul* d x)) | |
| (setq y (mul* d y)) | |
| (div (mod x y) d))) | |
| (t nil))) | |
| seems to fix this problem. After make, Maxima was then able to correctly evaluate | |
| sin(n %pi), sin(n %pi / 2), cos(n %pi), and cos(n %pi / 2), where n is declared to | |
| be an integer. | |

| Thank you for your help on substitutiion procedures, i managed to | |
| rearrange my expressions properly | |
| A questions about factoring out expressions in arrays: my aim is to factor out | |
| each element in dotdensity array, defined below. | |
| Each element in array dotdensity contains elements from array c. | |
| I should be able to factor out each element in dotdensity with respect to every | |
| elemnt in c, exept for the null ones. | |
| As an example take the element (1,1): | |
| (C11) dotdensity[1,1]; | |
| (D11) %I c cc V - %I cc c V | |
| 1 2 1 2 | |
| That should be factored into: %I V ( c cc - cc c ) | |
| 1 2 1 2 | |
| Since i do not which c parameters appear in dotdensity[i,j], i tried to factor out | |
| k | |
| with respect to every c , using the listarray function, but no luck. | |
| k | |
| Listarray(c) yields | |
| (C7) listarray(c); | |
| (D7) [0, 0] | |
| What is wrong? | |
| Is there another way to get the same results? | |
| thank you | |

| Hi, | |
| I'm trying to port Maxima for Darwin. First I need a Common LISP compiler. | |
| But I couldn't install GCL from sources... | |
| I wish I could have a minimal port with Maxima as a comand-line tool at | |
| least. So, I'm asking you: | |
| i) Is there a document describing what are the portions of Maxima and how to | |
| compile them step by step? | |
| ii) Is it possible to compile certain parts of Maxima with CLISP? Would it | |
| be functional? | |
| If somebody can answer me and somehow give me any hint, I'd really | |
| appreciate. I need some documentation mainly... | |
| Thanks in advance, | |
| Lizardo. | |

| Dear developers of Maxima, | |
| I have tried to compile gcl-2.4.0 under Red-Hat Linux 7.1 (gcc 2.96-81). | |
| The configure script seemed to work O.K., but at the end it writes the | |
| message | |
| "patching o/makefile for gcc bug in 2.96". | |
| When I run "make", it ends (after some work) with an error | |
| ... | |

| To make old code work, maxima accepts all of the original commands (defined | |
| in the base lisp) in any case. RatSimp, RATSIMP, ratsimp will all work. | |
| However for commands which are not in the base image, the case is important. | |
| Joe(x):=x+2; | |
| joe(x):=x+3; | |
| JOE(x):=x+4; | |
| will all be distinct functions. | |

| I am interested in obtaining solutions to equations involving exp(x), | |
| that is %E^x. | |
| For a very simple example, consider: | |
| (C1) h(x):=x*exp(-x); | |
| (C2) solve(h(x)=1/4); | |
| x | |
| %E | |
| (D2) [x = ---] | |
| 4 | |
| Of course, Maxima is correct to say that x=exp(x)/4 "solves" the above | |
| equation, but that is not really what one is looking for. | |
| Numerically, one can verify that x=0.36 and x= 2.15 would make | |
| h(x)=0.25. | |
| But, how to get Maxima to give this answer?? | |
| I tried different "switches" for "solve" but could not find anyone that | |
| would lead to a numerical solution. | |
| I also found and tried the function zsolve, whose description sounds | |
| promising, but could not get it to work. | |
| Unfortunately, this function appears to be undocumented. | |
| Thanks in advance for any suggestions! | |

| WOW! That was quick, Boris! It almost looks as if you sent your answer | |
| before I asked the question! :-) | |
| And it even works (I have already tried it)! | |
| I also found a way to get the other solution. | |
| Thank you very much! | |

| P.S. I am replying to the list in case someone else may want to know. | |
| It seems that Maxima's initial help/tutorial does not address the issue | |

| Hi, | |
| I have CLISP 2.25.1 running on Darwin (Mac OS 10.0.4). | |
| I wish you could help me porting it for Darwin: | |
| i) First, I don't have a Fortran compiler yet, hence, I think I won't be | |
| able to compile the numerical package, is it right? | |
| ii) Second, I want to disable the ploting features and xmaxima for the | |
| moment and just have a command-line tool. | |
| I couldn't find a good tutorial or HOWTO in order to build it and, so far, | |
| the README didn't say much, that's why I'm asking for help. | |
| I want to: | |
| a) Build "maxima" under the constraints above on my home directory and test | |
| it. | |
| b)Provide a Carbon application later on. | |
| I need some introductory remarks or ---even better--- a step by step | |
| tutorial describing each component of "src" directory and how to build it | |
| with CLISP (if possible ;). | |
| Any tip is welcome. | |
| Thanks in advance, | |
| Lizardo. | |

| Well, there's a "src/compile-clisp.lisp" file, what suggests that Maxima was | |
| already built using CLISP. Unfortunately it wasn't well documented. I | |
| searched in the mailing archives and couldn't find much too. | |
| Any tip would be great. | |

| First, try using ratsubst instead of subst: | |
| (C5) subst(omega23, chi * om23, chi^2 * om23^2 + 43); | |
| (D5) chi^2*om23^2+43 | |
| (C6) ratsubst(omega23, chi * om23, chi^2 * om23^2 + 43); | |
| (D6) omega23^2+43 | |
| If this doesn't work, you can instead try something like | |
| subst(omega23 / chi, om23, ...) | |

| P.S. Many thanks for the folks who helped me with Poisson and helped me | |
| find the format package the other week; format has worked well for me and it even | |
| contains an enhanced Poisson package. Finally, | |
| (setq machine-mantissa-precision (float-digits 1.0d0)) works for me. | |

| i) First, I don't have a Fortran compiler yet, hence, I think I won't be | |
| able to compile the numerical package, is it right? | |
| no it is not needed | |
| to compile under clisp: | |
| if the command to invoke clisp is 'clisp' | |
| cd src | |
| make clisp-compile CLISP=clisp | |
| and the xmaxima should be invoked with | |
| export MAXIMA_DIRECTORY=/home/wheretofind/maxima-5.6 | |
| xmaxima -lisp clisp | |

| Do you have any ideas? | |

| Some math-related software packages (e.g. Matlab) provide a "diary" | |
| option. This enables the user to request that a text file be created | |
| with a copy of a session, including all commands entered by the user | |
| and the corresponding replies by the software. | |
| This feature is convenient sometimes, although it may be substituted by | |
| conducting the session from within a text editor, such as e-macs. | |
| An even handier feature may be the generation of a (La-)TeX "diary", | |
| that is, a TeX file corresponding to user inputs and program outputs! | |
| Now, Maxima can provide TeX translation, one expression at a time | |
| (tex(%) for example). | |
| Can Maxima "automatically" generate: | |
| a) an ASCII (text) "diary" file | |
| b) a TeX "diary" file ? | |
| If (a) is available but not (b), it would seem desirable and relatively | |
| simple to extend (a) to (b) by way of the tex command. | |
| Thanks. | |
| __Virgil | |
| P.S. I am aware that an interface between TeXmacs and Maxima apparently | |
| exists and may provide some of the functionality of option (b) above. | |

| The command "writefile(filespecification);" | |
| has the diary function. | |
| you have to closefile() afterward. | |
| If you want each command to be TeX'd, I suppose it can be | |
| done by replacing the command-display function, perhaps | |
| found in the main loop of the "continue" lisp function in SUPRV1.lisp | |
| But first try this: | |
| writefile(texdiary); | |
| map(tex,reverse(labels)); | |
| closefile(); | |
| which might produce a tex'd diary of commands and displays. | |

| Hi, | |
| I'm running clisp 2.25.1 on Darwin 1.3.7 (Mac OS 10.0.4). | |
| Now I'm trying to port Maxima using CLISP, since GCL have been being hard to | |
| build. I know some of you already did it. I'm a newbie and need some | |
| directions here. | |
| Would somebody please could be kind enough to give me some instructions, | |
| kind of a recipe, or even a starting point? | |
| So far I did | |
| cd src | |
| make clisp-compile CLISP=clisp | |
| I got a couple of warning and no errors, but Maxima isn't working. That's | |
| what I get retrying "make": | |
| ; Loading file macsys.fas ... | |
| ;; Loading of file macsys.fas is finished. | |
| ;; Loading file mload.fas ... | |

| I am interested in the related project of running Maxima on a PowerPC | |
| Macintosh operating under LinuxPPC 2000Q4. | |
| I already have installed CLISP and it appears to be running well. | |
| I would prefer to find a ppp.rpm file of Maxima 5.6, but it appears | |
| that no one has made it available on the web. | |
| In any case, if anyone has successfully installed Maxima 5.6 on | |
| LinuxPPC (or another distribution for the PPC chip), and is willing to | |
| provide advise or guidelines, please let me know. Please, reply to my | |
| e-mail. I'll send a summary of my experience to the list later on. | |
| Thanks in advance. | |

| I have clisp-2.26 running on SGI Irix 6.5. After changing two | |
| lines in clisp-compile.lisp I get stuck at the same message. | |
| For the record, the changes were simply to replace "lisp:..." with | |
| "ext:...": | |
| ; (lisp:gc) | |
| ; (lisp:saveinitmem "maxima-clisp.mem" | |
| ; :init-function #'user::run) | |
| (ext:gc) | |
| (ext:saveinitmem "maxima-clisp.mem" | |
| :init-function #'user::run) | |
| The block that appears to be the problem in suprv1.lisp is: | |
| (cond (#-cl (< (cadr x) | |
| 160) | |
| #+cl (char< (cadr x) | |
| #. (code-char 160.)) | |
| (ASCII (CADR X))) | |
| (t (cadr x))))) | |
| In clisp I get: | |
| [1]> (code-char 160.) | |
| #\NO-BREAK_SPACE | |
| I don't know where the "NO-BREAK_SPACE" is defined, and I wonder | |
| if it shouldn't be "NO_BREAK_SPACE", or if it is really needed | |
| at all for maxima. | |

| For whatever reason, writefile(myfile) [or writefile("myfile")] does | |
| create the file "myfile"...but NOTHING is added to the file. (This has | |
| nothing to do with TeX) | |
| For example, the session below, results in the creation of the file | |
| "texdiary2" in my home directory, but it remains empty *after* the | |
| closefile() command. | |
| (C6) writefile("texdiary2"); | |
| Starts dribbling to texdiary2 (2001/7/10, 12:52:1). | |
| (D6) FALSE | |
| (C7) integrate(x/(1+x^3),x); | |
| 2 x - 1 | |
| 2 ATAN(-------) | |
| LOG(x - x + 1) SQRT(3) LOG(x + 1) | |
| (D7) --------------- + ------------- - ---------- | |
| 6 SQRT(3) 3 | |
| (C8) diff(tan(x),x); | |
| 2 | |
| (D8) SEC (x) | |
| (C9) solve(x^2-5*x+6=0,x); | |
| (D9) [x = 3, x = 2] | |
| (C10) closefile(); | |
| Finished dribbling to texdiary2. | |
| (D10) FALSE | |

| Hi, | |
| I'm trying to port GCL, a COMMON LISP compiler, | |
| ftp://ftp.ma.utexas.edu/pub/gcl/gcl-2.4.0.tgz | |
| I'll use it to build Maxima, | |
| http://www.ma.utexas.edu/users/wfs/maxima.html | |
| sort of a Maple and Mathematica clone. | |
| Unfortunately, my experience with GNU tools is restricted to the | |
| compilation of numerical programs in C and Fortran. So, if you're | |
| interested in one of these packages and want to help me, I'd really | |
| appreciate. | |
| PLEASE, give me a reply if you have any ideas and I apologize for | |
| bothering some of you... | |
| Below is what I've done so far (I know there are easier ways to do it ): | |
| First, edit the "FreeBSD.defs" located at the "<Where you keep GCL>/h" | |
| folder according to Darwin and its compiler (I can send you a copy of | |
| mine.) | |
| In the directory "<where you keep GCL>" type | |
| # ./add-defs FreeBSD | |
| #make -n | |
| and you'll see what steps "make" shall attempt to do | |
| #cd bin | |
| edit "Makefile" according to folders and compiler. | |
| #make | |
| Shouldl run without errors... | |
| #cd.. | |
| Now follow " make mpfiles -n ". First, | |
| #cp -v /usr/libexec/con* < Where you keep GCL and path>/gmp | |
| That will replace "config.guess" and "config.sub" in the folder above. | |
| #cd gmp; ./configure | |
| #cd .. | |
| # make mpfiles -k | |
| and you'll get several syntax errors during the compilation of files *.s | |
| ( An example: | |
| #cc -c -DHAVE_CONFIG_H -I. -I. -I.. -I.. -DOPERATION_rshift -g -O2 | |
| -mpowerpc tmp-rshift.s -o rshift.o ) | |
| Finally, | |
| #cd o | |
| Edit Makefile | |
| #make -k | |
| There are 4 files that should be compiled yet... | |
| We could go further, but should heal "make mpfiles" first... I'm sure | |
| that somebody will come up with something that should work. | |
| Thanks, | |
| Lizardo. | |

| I tried this, but now get the error: | |
| ;; Loading file suprv1.fas ... | |
| *** - CHAR-CODE: argument (CNTLC #\Etx) is not a character | |
| Bye. | |
| I think the replacement should read: | |
| #+cl (< (char-code (cadr x)) 160) | |
| With this, compilation proceeds much further, but stops at: | |
| Compiling file /disk2/gwhite/src/maxima-5.6/src/mactex.lisp ... | |
| *** - READ from #<BUFFERED FILE-STREAM CHARACTER | |
| #P"/disk2/gwhite/src/maxima-5.6/src/mactex.lisp" @1>: illegal character | |
| #\Us | |
| Bye. | |
| The file mactex.lisp appears to be corrupt. It is 9289 bytes, dated May | |
| 18 06:26. I had a version that is 26076 bytes from Apr 2 20:19. | |
| With this change, I was able to get a maxima-clisp.mem, but there is | |
| a problem with the tests: | |
| (cd ../doc ; clisp -M ../src/maxima-clisp.mem tests.lisp) | |
| *** - READ from #<BUFFERED FILE-STREAM CHARACTER #P"tests.lisp" @10>: | |
| there is no package with name "SI" | |
| gmake: *** [test-clisp] Error 1 | |
| I can, however, run simple examples, e.g., cut and pasted from the | |
| manual.demo file. | |

| Hi, | |
| If this is too OFF_TOPIC, please let me know... | |
| I downloaded "a.out.h" from the Internet and now there are just for 2 files | |
| that should be compiled in the "<Where you keep GCL folder>/o": | |
| i) unixsave.c ( it can't find unexec.c and other errors... ) | |
| ii) sfals.c ( in FreeBSD.h there's RELOC_FILE="rel_sun3.c ") | |
| I don't know what would be the right RELOC_FILE for Darwin. | |
| Also, if somebody have any idea and want to help me somehow, I'd really | |
| appreciate... | |
| Thanks in advance, | |
| LIzardo. | |
| P.S.: " make mpfiles -n " says nothing to be done for all; but | |
| #cd < ... GCL folder>/gmp/mpn | |
| #make -n | |
| Says that I have to compile a couple of "*.s" sources... Problems with that? | |

| Common Lisp is by default case insensitive. This is a really | |
| bad design decision, in my opinion, and I objected to it | |
| when it was proposed that way by people at MIT and Stanford and CMU who | |
| had extensive experience with Maclisp and other case-insensitive | |
| lisps of the 1960's. But they prevailed. People with Unix experience | |
| who enjoyed BOTH cases, lost. | |
| Indeed Macsyma was written originally in Maclisp which was | |
| case insensitive. This was on DEC PDP-6 and DEC-10 systems with | |
| 36 bit words where every bit counted. | |

| Hi, | |
| Following the messages that William and George exchanged, I could edit | |
| "suprv1.lisp" and reach the final of the Maxima compilation without | |
| warnings. | |
| Now I want to test it and finalize. If you could please tell me what to | |
| do I'd really appreciate. | |

| I have just learned | |
| that there will be a release of Allegro Common Lisp 6.1beta | |
| on OS-X from Franz Inc very shortly. | |
| Using it would put the burden of support of the Lisp on a commercial | |
| outfit instead of volunteers. It would not, however, be free. | |
| There is some conditionalization for Allegro in the Maxima code, | |
| but I have not tried to recompile it in its entirely in Allegro | |
| for some time. | |
| There are undoubtedly points of comparison among GCL, CLISP | |
| and Allegro other than price. | |

| The point is that I can't afford a commercial package. | |
| Yet, I'm not acquainted to COMMON LISP and it's hard to port MAXIMA with | |
| CLISP while I can't find much documentation. (If somebody could address | |
| me...) | |
| But I still think that Maxima would be a great package for Mac OS X, given | |
| the facilities OSX has... | |

| I'm not going do discuss about your time, but about mine, since, as you | |
| said, you're a volunteer and just help me if you want. | |
| I only regret that free softwares available aren't in general well | |
| documented for beginners like me. But this kind of attitude is changing | |
| fast. | |
| I think it's justifiable to waist some of time in a project which | |
| universities like mine would be able to profit. In fact, I don't believe | |
| that using free tools to build a nice package like Maxima for uncommon | |
| platforms like mine is a big waist of time. | |
| But yes, maybe I'm underrating my time... | |

| The standard install is for gcl. | |
| You can just leave maxima where you built it, or move the directory... | |
| To invoke maxima you must tell it where the documentation and files are | |
| the easiest is to set an environment variable and then invoke the command. | |
| You can make a shell script: | |
| eg: | |
| ==================maxima============== | |
| #!/bin/bash | |
| export MAXIMA_DIRECTORY | |
| MAXIMA_DIRECTORY=/directory-where-i-put-it/maxima-5.6 | |
| exec clisp -M ${MAXIMA_DIRECTORY}/src/maxima-clisp.mem | |
| ===================== | |
| ===============xmaxima=================== | |
| #!/bin/bash | |
| export MAXIMA_DIRECTORY | |
| MAXIMA_DIRECTORY=/directory-where-i-put-it/maxima-5.6 | |
| exec ${MAXIMA_DIRECTORY}/bin/xmaxima -lisp clisp | |

| I'm a MAXIMA beginner and I'like to know | |
| - if is possible to apply the trigreduce to a matrix to trig reduce every | |
| term of the matrix and, | |
| - How can I get a full trigreduce of a expression A, something to do : | |
| trigreduce(trigreduce(trigreduce(A))), in a direct way. | |
| Thanks, | |
| yours, | |

| Greetings! I've been looking at a number of the numerical routines | |
| listed by the info pages as accessible under maxima, but I can't get | |
| any of them to work. Like zsolve, for example. Are these routines | |
| still available? | |
| If not, is there any other convenient way to numerically, rather than | |
| symbolically, process a given stage of a maxima session? Can one for | |
| example approximate the root of d=%E^d-1.5? | |
| Is there any interest in providing some numerical functions, say from | |
| the gsl library, under maxima? If so, is there a howto or simple | |
| example? I could probably add what I need. | |
| Take care, | |

| Hi Camm, | |
| Certainly! At the beginning of a session, type numer:true - this will let | |
| you do nearly everything in floating point. There is a routine in the share | |
| directory for Newton's method for your nonlinear equation. I've done a few | |
| numerical routines by essentially transcribing published Fortran or C codes. | |

| Just a suggestion. Possibly most people use Latex rather than Tex. I | |

| with latex ... | |
| In this case the tex function could be improved or maybe created a | |

| incredibly smooth and also that the Tex output from Maxima is | |
| ABSOLUTELY better than the equivalent Mathematica function. | |

| Hi, | |
| I just downloaded and installed the latest releases of GCL-2.4.0 and | |
| Maxima-5.6 on a RedHat 7.1/i386. I ran into a couple of problems. | |
| In the configure script for GCL, there's a little EMACS function which tries | |
| to find the site-lisp, defaults.el and lisp info/dir. In the version of EMACS | |
| which is shipped with RH 7.1, EMACS produces different output from what is | |
| expected by the sed command, namely: | |
| [root@guanaco gcl-2.4.0]# emacs -q -batch -l conftest.el | |
| Loading /usr/share/emacs/site-lisp/site-start.d/aspell-init.el (source)... | |
| Loading /usr/share/emacs/site-lisp/site-start.d/lang.emacs.el (source)... | |
| Loading /usr/share/emacs/site-lisp/site-start.d/po-mode-init.el (source)... | |
| Loading /usr/share/emacs/site-lisp/site-start.d/psgml-init.el (source)... | |
| Finished loading /usr/share/emacs/site-lisp/egg/leim-list.el | |
| and load others... | |
| ./default.el | |
| The 'Finished loading..' and ' and load others...' are not properly filtered | |
| out by the sed command. (So, I changed it to 'sed -e /[Ll]oad/' in each of | |
| three places this is used and it got through configure OK.) | |
| After I built Maxima, I was trying out some old .mc files and I found that | |
| integration seems to be broken. For example: | |
| [root@guanaco gcl-2.4.0]# maxima | |
| GCL (GNU Common Lisp) Version(2.4.0) Tue Jul 17 15:59:50 EDT 2001 | |
| Licensed under GNU Library General Public License | |
| Contains Enhancements by W. Schelter | |
| Maxima 5.6 Tue Jul 17 15:59:47 EDT 2001 (with enhancements by W. Schelter). | |
| Licensed under the GNU Public License (see file COPYING) | |
| (C1) integrate( exp( x ), x, x1, x2 ); | |
| (D1) x2 - x1 | |
| ((C2) integrate( x, x, x1, x2 ); | |
| 2 2 2 2 | |
| x2 FALSE x1 FALSE | |
| (D2) ---------- - ---------- | |
| 2 2 | |
| (C3) quit(); | |
| I then downloaded the latest snapshot of Maxima. This would not complete | |
| compilation because the file src/mactex.lisp appears to contain binary data. | |
| Whew. It's not been my day. | |
| Thanks, | |
| Allen | |

| Hi - I still haven't figured out myself how to plot discrete data points | |
| with Maxima, which I think is what you're trying to do. The problem lies | |
| with the plotting, not Newton. Sorry... Dave Holmgren | |

| How can i execute a maxima script from the command line? i've been looking in the manual and can find any reference to the maxima arguments. What i want to know is if there is some way to run maxima like: | |
| maxima -f script.max | |
| and then it loads the file without having to enter maxima manually and run the script with BASH(). | |

| z(c):=NEWTON(%E^d-d-c,d,1.0,0.01) fails because, it seems to me, you | |
| cannot define a "generic" function in terms of the newton function | |
| applied with an unknown parameter. | |
| I believe I did something similar to what you want by using: | |
| i) create_list | |
| ii) openplot_curves | |
| It would go something like: | |
| load("newton"); | |
| cpts:create_list(j/10,j,12,23); | |
| pts:create_list([c,NEWTON(%E^d-d-c,d,1.0,0.001)],c,cpts); | |
| openplot_curves([pts]); | |

| I compiled Maxima following the steps below in "./src": | |
| # make clisp-compile CLISP=clisp | |
| # make maxima-clisp.mem CLISP=clisp | |
| # make test-clisp CLISP=clisp | |
| Yet, I can't use xmaxima, omplotdata and so forth. It seems I've skiped a | |
| couple of steps or something escapes me; for instance, I can't use plot2d(). | |
| Any help is welcome. | |

| Greetings! First let me preface this by saying that maxima is more | |
| than fast enough for my needs, and that I haven't as yet fully | |
| explored all its functionality. But I did notice the discussion on | |
| bignums, and how gcl/maxima can now benefit from the enhanced | |
| performance offered by gmp. My questions: | |
| 1) Could maxima realistically benefit from using optimized blas | |
| routines, as does octave? | |
| 2) Could maxima realistically benefit from using MPI and running over | |
| a cluster? | |
| Obviously, the answer to 1 and 2 could only be yes with a problem size | |
| much much larger than anything I personally have seen so far. I'm | |
| just interested if any other users have seen such large problems. | |
| Separately | |
| 3) Is there any way to use gcl as a stand-alone compiler, making object | |
| files which can be linked with fortran and C object files into the | |
| final executable? It seems as though the way to use gcl to make a | |
| stand-alone program such as maxima is rather by dumping its memory | |
| image or some such after loading the maxima lisp source. | |
| Take care, | |

| 1) Could maxima realistically benefit from using optimized blas | |
| routines, as does octave? | |
| Maxima does not have much numerical code, for such computations octave | |
| is better and it is also covered by the GNU license. It might be | |
| good to add code to invoke the fortran routines: I once made a file | |
| ( src/fortdef.lisp) which set up calls to a subsidiary fortran program | |
| using xdr data exchange. I am afraid I dont know if this still works, | |
| see the example at the end of that file. | |
| 2) Could maxima realistically benefit from using MPI and running over | |
| a cluster? | |
| I think it will in the long run, and I will be making gcl have multiprocessor | |
| abilities, sometime in the coming year. Then we will have to find appropriate | |
| places to use this in maxima. | |
| 3) Is there any way to use gcl as a stand-alone compiler, making object | |
| files which can be linked with fortran and C object files into the | |
| final executable? It seems as though the way to use gcl to make a .. | |
| You can of course compile lisp files and load them with 'load'. If you | |
| want these to reference some external C or fortran then that C or fortran | |
| has to be linked into the base image (by adding it to the list of files | |
| at link time when gcl/maxima is built). You can compile lisp files and | |
| link them together: that is how gcl is built, all the .c files in the lsp and | |
| cmpnew directories are compiled from .lsp files, and then compiled with gcc | |
| and then linked into the image. Any program that is going to run however | |
| will need things like the garbage collector, storage allocation, bignum routines | |
| etc linked in ... ie basically the files of gcl. | |
| Hope this answers the questions at least somewhat. | |

| I used CLISP to get Maxima working for Darwin. It works fine, except for the | |
| fact that I can't use plotting features. | |
| For instance, | |
| (C1) plot2d(sin(x), [x,-5,5]); | |
| zsh: command not found: omplotdata | |
| (D1) | |
| I wonder what I have to do in order to get it working. I have XFree 4.0.2 | |
| and tclsh8.3 | |
| Thanks in advance, | |
| Lizardo. | |

| Maxima does run in Allegro, which now has various multiprocessing | |
| capabilities. | |
| The search for appropriate places to use parallelism | |
| in computer algebra has been going on for at least 30 years, with | |
| very limited success. There are some opportunities for conversion | |
| of symbolic questions into questions in linear algebra where parallel | |
| algorithms have been deployed (numerical routines), so maybe there | |
| will be some hope for the future. There are parallel Grobner | |
| basis fans, but even best-case linear speedup of an exponential cost | |
| algorithm | |
| tends to have limits. | |

| So far as I know, all TeX commands related to equations work identically | |
| in LaTex. I don't understand the error message about the } ... I cut | |
| and pasted the answer into emacs and found the {} to be balanced. | |
| There is a possibility of improving the appearance by adding small | |
| spaces; the source code would certainly allow the replacements | |
| of 1\over2 etc by \frac{1}{2}, but this would break the code | |
| for users of TeX. A command latex in addition to tex could | |

| I'm new to maxima and i'm finding the manual really confusing! | |
| I want to be able to save a 2d or 3d plot without using interaction (the plot window's menu). What i need is to be able to write a script file that plots a function in to a postscript file (or any other graphical format). How can i make this?, is there a place where i can find other maxima docs? | |
| Thanks for your help. | |

| Hi - You can use plot2dps in the same way as plot2d, and you can also put | |
| all of your Maxima commands into a text file which you can run in the | |
| following way: batch("c:\blah.mc"); where blah.mc is the text file. You | |
| also have to use the closeps command to initialize and terminate the | |
| plot(s). I hope this helps... | |

| Hi, | |
| I'm learning my way around Maxima. | |
| I would like to assign the results of the solution of a simultaneous equation | |
| to variables for later use. Is there a more elegant way than this: | |
| r:linsolve( [B2*du + A2* dv = dx, c2*du + D2 * dv = 0], [du,dv] ); | |
| du:rhs( first( r ) ); | |
| dv:rhs( last( r ) ); | |
| thanks, | |
| Adam | |

| Greetings. | |
| The code that I am about to refer to is included at the end of this | |
| message. I am running MAXIMA on a SuSE Linux 7.1 system. I installed | |
| it from | |
| maxima-5.4-1.i386.rpm. | |
| What does the following output from linsolve mean? | |
| (C79) vvs : LINSOLVE(L, vs) | |
| Dependent equations eliminated: (4 7 63 79 94 108 121 133 144 64 80 95 109 122 134 65 81 96 110 123 66 | |
| 82 97 111 67 83 98 2 6 84 85 86 115) | |
| Inconsistent equations: $ERREXP1 | |
| -- an error. Quitting. To debug this try DEBUGMODE(TRUE);) | |
| (C80) PRINT(ERREXP1); | |
| Error: Caught fatal error [memory may be damaged] | |
| Fast links are on: do (si::use-fast-links nil) for debugging | |
| Error signalled by CATCH. | |
| Broken at MACSYMA-TOP-LEVEL. Type :H for Help. | |
| Why doesn't it display the inconsistent equations by number as is | |
| usually the case? What should I make of ERREXP1 and the error message | |
| that appears when I try to access it? | |
| Thanks in advance for your help, | |

| I am having some trouble when I try to simplify certain trigonometic | |
| expressions | |
| For instance: after a loop using rotation matrices I obtain a matrix | |
| with elements like | |
| [ COS(q4 + q3 + q2 + q1) + COS(q4 + q3 + q2 - q1) ] | |
| [ ----------------------------------------------- ] | |
| [ 2 ] | |
| [ ] | |
| (D46) Col 1 = [ SIN(q4 + q3 + q2 + q1) - SIN(q4 + q3 + q2 - q1) ] | |
| [ ----------------------------------------------- ] | |
| [ 2 ] | |
| [ ] | |
| [ SIN(q4 + q3 + q2) ] | |
| but I could not obtain a simpler expression like | |
| [ cos(q4+q3+q2)*cos(q1)] | |
| [ sin(q4+q3+q2)*cos(q1)] | |
| [ sin(q4+q3+q2) ] | |
| which I intend to make another substitution like | |
| [c234*c1] | |
| [s234*c1] | |
| [s234 ] | |
| as the process fails at the first time the result becomes incredibly | |
| large. | |

| Hi, | |
| I'm still working on a system of differntial equations for describing | |
| fluid phenomenas. MAXIMA is a good help for solving these. Is there | |
| any LISP module for output into C instead of FORTRAN ? | |
| Thanks, Harald | |

| Hello again, | |
| First a question: I am trying to test some complicated inequalities. | |
| Since they don't seem to be true in general, I need to figure out the | |
| conditions on k, ka and kc which make them true. I'm wondering if there | |
| is some easier way to do this than assume() and is() and lots of | |
| intervention? Do we have something like a whenis() function, which | |
| would return a set of conditions under which an inequality holds? | |
| Second, I think that I may have found a problem with Maxima's reasoning: | |
| I wonder if this is a bug, or whether I'm expecting too much of Maxima. | |
| C28 is true, as it should be. I think C29 should be true, too, by | |
| transitivity and C31. I added curly-braces in D30; they should line up | |
| vertically, for in case the formatting gets messed up. | |
| (C28) is(3*k-1<kc); | |
| (D28) TRUE | |
| (C29) is(3*k-1<2*kc); | |
| MACSYMA was unable to evaluate the predicate: | |
| ERREXP1 | |
| -- an error. Quitting. To debug this try DEBUGMODE(TRUE);) | |
| (C30) facts(initial); | |
| {2 - ka } {kc + 1 } { 3 k } | |
| (D30) [kc + ka - 1 > 0, 1 > ka, 1 > kc, k > {------}, {------} > k,{ | |
| ---} > kc, | |
| { 3 } { 3 } { 2 } | |
| ka + 3 k - 2 > 0, kc - 3 k + 1 > 0, kc > 0] | |
| (C31) is(kc<2*kc); | |
| (D31) TRUE | |
| (C32) is(3*k-1<2*kc); | |
| MACSYMA was unable to evaluate the predicate: | |
| ERREXP1 | |
| -- an error. Quitting. To debug this try DEBUGMODE(TRUE);) | |
| (C33) | |
| By the way, this is Maxima 5.6 on gcl 2.4 on Redhat 7.1. | |
| Thanks, | |
| Nels | |

| Hello list, | |
| I would like to use the function expand_wrt. | |
| According to the docs, I should do a LOAD(STOPEX); . | |
| So I do that, but this gives me: | |

| Dear List-members, | |
| Acc. to an article in Fibonacci Quarterly Vol.37.2, May 1991, | |
| the geometry of the Fibonacciseries is a hyperbola with asymp- | |
| totes x = -2 and x + y = 1. I would very much like to know the | |
| equations and the excentricity of this hyperbola. | |
| I would also like to know the solutions to the following two | |
| equations hopefully giving the reason for their differnce: | |
| a. x^2 + 2x + y^2 = -2 {ؠ(Empty Set)} | |
| b. x^2 + 2x + y^2 = -1 {point (-1,0)} | |
| Sincerely | |
| Raoul Martens | |

| Greetings. | |
| Rewrite these two equations as | |
| (x+1)^2 + y^2 = -1 | |
| (x+1)^2 + y^2 = 0. | |
| Real squares are positive, so the first one cannot be solved. The | |
| second one implies that x+1=y=0. | |

| Greetings, | |
| First, thanks a lot to whoever adopted maxima to run under | |
| cmucl. There were however still a few quirks I had to bypass for it to | |
| actually run correctly, this made me wonder if I should look for newer | |
| cmucl specific patches? I didn't have much luck with the CVS | |
| version. Anyway, bypassing the quirks, maxima passes all the tests in | |
| doc/tests.lisp, and blazingly fast:-) | |
| Here is a summary of my fixes, intermixed with relevant diffs: | |
| * *QUO is declared to be inline and ftype (function (* *) *), while | |
| actually being ftype (function (number number) (values number | |
| &optional integer)) This combination caused cmucl 18c x86f to | |
| generate incorrect code, assuming the function would never be | |
| called with integer arguments. The symptom of this was the COMPPI | |
| function never returning. Putting a PROGN around the TRUNCATE to | |
| explicitly get rid of the extra return value solves the problem | |

| during one lisp session, some DEFMACROs in hyp.lisp (notably MABS) | |
| remains defined in the restarted image. This is apparently not the | |
| intention, see EVAL-WHEN in hyp.lisp. The symptom here is simple | |
| expressions like x:0.1; abs(x^2-10); throwing a lisp error. I guess | |
| it would be possible to explicitly undefine macros before saving the | |
| image. A simpler solution is to quit cmucl after (COMPILE-MAXIMA), | |
| then restart cmucl, run (COMPILE-MAXIMA) (This loads the already | |
| compiled hyp.x86f respecting the intention of its EVAL-WHEN) and | |
| finally (SAVE-MAXIMA) | |
| * cmucl doesn't have EVALHOOK, thus :lisp from the maxima prompt | |
| fails. This fix is probably not complete wrt *break-env* and | |
| friends. | |

| So you got the basics to work without the problems I had? IIRC, you're | |
| on sparc and run cmucl from CVS, that could be the reason. | |

| I'm wondering: If I compile a file containing, | |
| (eval-when (eval compile) (defmacro foo ...) ...), | |
| is it correct for FOO to be defined as a macro in the lisp image where | |

| Hello, | |
| I'm new with this and finding it hard to learn how to use | |
| Maxima with the info page and manual. Do you know of any | |
| introductory manuals or tutorials? Also, has anyone posted | |
| maxima code on varied (simple) problems so one can learn from | |
| looking at it? If not is anyone willing to do this? | |
| Thanks, | |

| Friends: | |
| Maxima/GCL users: | |
| I heard from a colleague, and then | |
| confirmed via Prof Robert Boyer at UTexas, that | |
| Bill Schelter died. The last message I saw, | |
| sent from Russia, was dated July 26. | |
| Here is the note I received from Bob Boyer... | |
| .................... | |
| It is so very sad but true, Bill Schelter has died. | |
| Bill went to Moscow, this summer, got married, and died of a heart | |
| attack at | |
| the end of July. He was buried in Canada a few weeks ago. | |
| His wife is named Olga Vodianikova, but I don't have an address for her. | |
| His daughter can be reached at | |
| Mike and Karen Schelter Lewis | |
| 1705 Autumn Fire Drive | |
| Cedar Park, TX 78613 | |
| His son Johh, a med student, can also be reached at that address. | |
| >From what little I know, Prof. Michael Artin, [email protected], may be the | |
| person most up-to-date on the details of the story. | |
| Sincerely, | |
| Bob Boyer | |

| I never meet Bill Schelter, but he answered my questions about maxima | |
| accurately, quickly, and respectfully. I'll remember him for that. The | |

| I just read this news yesterday, and have been deeply saddened by it | |
| ever since. I never had the honor of meeting Dr. Schelter in person, | |
| but I knew him via email as an extremely helpful, outstandingly | |
| knowledgeable, persevering and diligent servant to the mathematical | |
| education and empowerment of the public. To say that he will be | |
| missed doesn't begin to do justice to our loss. In him resided a | |
| confluence of skills and will which, quite honestly, I haven't even | |
| the slightest vision of how they can be replaced. And this is indeed | |
| tragic, as I feel he would be most gratified to know that his gift to | |
| humanity would live beyond him. Perhaps, in time, a small army might | |
| be found to attempt to fill his shoes, however inadequately. | |

| Are these errors from "make test" normal for maxima 5.6 with gcl | |

| 1. For no errors under RedHat 6.2, I had to add at least one kill(all) | |
| statement to the | |
| rtest*.mac files (in particular to rtest4.mac). With more RAM, this might | |
| not be needed. | |
| 2. Some maxima-5.6 RPMs you find on the web are broken; try building | |
| maxima | |
| from the latest development sources (there are several maxima-5.6 | |
| versions). | |

| For what it's worth, I've been getting similar errors (about 20 of them) | |
| when running the checks. Seems to be mostly in the integration | |
| routines, but I haven't had time to dig into it, since I don't need it | |
| right now. I've had this problem with Mandrake 8.1, and Redhat 7.1, | |
| with Maxima 5.6. | |
| Hope this helps, | |

| OK, I tried the kill(all) suggestion in rtest3.mac. I got | |
| the same results. I tried recompiling from the Maxima most | |
| recent source (from the main Maxima page, which is also where | |
| I got my 5.6 tarball) and got exactly the same 'make test' | |
| results. | |
| Here's one example of a broken test. | |
| /* ********************** Problem 89. *************** */ | |
| %Input is | |
| INTEGRATE(EXP, X) | |
| Division by 0 | |
| -- an error. Quitting. To debug this try DEBUGMODE(TRUE);) | |
| Caused a error break: rtest3.mac | |
| Error Summary: [BROKE, (QUOTE, rtest3)] | |
| Since the error output said to try DEBUGMODE(TRUE), I added | |
| debugmode(true); | |
| done; | |
| in rtest3.mac just before the failing test. Rerunning the | |
| test produced (just the bad parts): | |
| /* ********************** Problem 90. *************** */ | |
| %Input is | |
| INTEGRATE(EXP, X) | |
| Division by 0 | |
| -- an error. Entering the Maxima Debugger dbm | |
| (dbm:1) | |
| FALSE | |
| (dbm:1) | |
| FALSE | |
| (dbm:1) | |
| FALSE | |
| The (dbm:1) FALSE pattern continues seemingly forever. | |
| Any ideas people? Many thanks.... | |

| I've solved the problem of compiling gcl and maxima on Mandrake | |
| 8.0 and getting all the self-tests to pass. Forgive me while | |
| I waste some bandwidth in order to get this solution into the | |
| mailing list archive. I hope that will help someone in the | |
| future and maybe even prevent future bandwidth wasting. ;-) | |
| A half-dozen or so folks contacted me off list. All indicated | |
| that gcl & maxima should compile on Linux and that "make test" | |
| should pass all tests. No one had a specific solution. Some | |
| assumed that I'm running Redhat and mentioned that gcc-2.96 | |
| can cause some tests to fail. I run Mandrake 8.0 which, like | |
| Redhat, uses the "controversial" gcc-2.96 compiler. Luckily | |
| the kernel needs a working compiler. On Mandrake 8, this is in | |
| /usr/bin/kgcc and is "gcc version egcs-2.91.66". I took all this | |
| advice and read all about Redhat in h/386-linux.defs. | |
| What I needed to do (leaving out a few details) is: | |
| - configure gcl with CC=kgcc | |
| - hand craft the gcl-2.2.2_rh50linux.patch to work with | |
| gcl-2.4.0. | |
| - patch 386-linux.defs to make sure that "-static" is turned on | |
| in the "LDCC=${CC} -static" line. | |
| - make gcl with GCC=kgcc and OFLAG=-g | |
| - configure maxima with CC=kgcc | |
| - make maxima with GCC=kgcc | |
| As for those few details, I've attached my RPM spec files for | |
| gcl and maxima and the small patch files they reference. | |
| Cheerio... | |

| Greetings, and thanks for posting this! I'm glad you got it working, | |
| but it seems that what you had to do is quite sad. You basically had | |
| to turn off all optimization, and make a static binary. I maintain | |
| the maxima package for Debian, and Dr. Schelter had helped me address | |
| most of these issues a long time ago. The package currently produces | |
| a stripped, dynamically linked binary with compiler optimization that | |
| passes all tests using gcc 2.95. I'm only telling you this in case | |
| you might want to pursue this further. You can download the tar.gz | |
| and diff.gz source files for maxima from the Debian website, unpack | |
| the tar file, and apply the diff with the patch program. You could | |
| then examine the differences in the config files from those in | |
| your source tree. In any case, kgcc on your distro is a good idea. | |
| But if you'd like to contribute your rpm to mandrake or otherwise | |
| distribute it, it would be best if it could be optimized, stripped, | |
| and dynamically linked. | |
| P.S. I had thought that all the changes Dr. Schelter had given me | |
| relating to these issues were included in cvs. I'll try to confirm | |
| this when I get a chance. | |
| P.P.S. Does anyone know if the cvs tree for maxima and gcl will remain | |
| at their current locations? As far as I knew, Dr. Schelter was the | |
| only one with write access. | |
| Take care, | |

| Yes, both maxima and gcl repository will stay in their | |
| current location indefinitely. If someone (or a group) | |
| wants to take over the responsibility of maintaining these | |
| packages, I'll be more than happy to help making the repository | |

| OK, I think I've got a better solution. I turned the | |
| optimization and dynamic linking back on and everything | |
| still passes "make test". The main problems seems to be | |
| that gcc 2.96 doesn't produce good code. My solution for | |
| that is to use /usr/bin/kgcc. If anyone wants my RPM | |
| spec files for gcl and/or maxima, please write and I'll | |
| send them to you. If there are too many requests, then | |
| I'll send them to the list again. | |
| Cheers.... | |

| This sounds bit of strange to me... I have had no problems with | |
| Slackware 7.1 + maxima 5.6 (I think the last cvs tree I downloaded | |
| was more or less in july, but sorry not to remember) + gcl 2.4.0 | |
| (also not remember the date)... egcs-1.1.2 Pentium III 933Mhz + 128Mb | |
| runs all the tests OK. | |
| Hope this may help to enlighten things a bit. | |
| Regards, | |
| Pedro. | |

| The fact that you used egcs-1.1.2 to compile would make me | |
| think everything would test fine. I believe the problem is | |
| with gcc-2.96 specificly. If I avoid that version of the | |
| compiler, then I have no problems. | |

| 1. Load vect.mc from the share directory; vector.mc in the share2 | |
| directory is broken. | |
| 2. In vect.mc, I had to change the two define_variable statements from | |
| DEFINE_VARIABLE(sfprod,1,any)$ | |
| DEFINE_VARIABLE(sf,[1,1,1],list)$ | |
| to | |
| DEFINE_VARIABLE(SFPROD,1,any)$ | |
| DEFINE_VARIABLE(SF,[1,1,1],list)$ | |
| (I don't understand why SF and SFPROD must be uppercase here; with my | |
| maxima, they do need to be.) | |
| 3. Try the following: | |
| (C1) load("vect.mc"); | |
| Warning - you are redefining the MACSYMA function TRIGSIMP | |
| Warning - you are redefining the MACSYMA function IMPROVE | |
| Warning - you are redefining the MACSYMA function UPDATE | |
| (D1) vect.mc | |
| /* By default, the coordinate system is cartesian with coordinates | |
| X,Y, and Z (upper case, not lower case) */ | |
| (C2) grad(X^2 + Y^2); | |
| 2 2 | |
| (D2) GRAD (Y + X ) | |
| (C3) express(%); | |
| d 2 2 d 2 2 d 2 2 | |
| (D3) [-- (Y + X ), -- (Y + X ), -- (Y + X )] | |
| dX dY dZ | |
| (C4) ev(%,diff); | |
| (D4) [2 X, 2 Y, 0] | |
| (C5) | |
| 4. There is some documentation in vect.usg; compared to the rest of maxima, the | |
| vector code isn't as well tested. I'd be careful about trusting it for much more | |
| than homework. | |
