Perfect sinc interpolation in Matlab and Python
% From http://phaseportrait.blogspot.com/2008/06/sinc-interpolation-in-matlab.html
% Ideally "resamples" x vector from s to u by sinc interpolation
function y = sinc_interp(x,s,u)
% Interpolates x sampled sampled at "s" instants
% Output y is sampled at "u" instants ("u" for "upsampled")
% (EXPECTS x, s, and u to be ROW VECTORS!!)
% Find the period of the undersampled signal
T = s(2)-s(1);

Various PRNGs, implemented in javascript.
// Linear Congruential Generator
// Variant of a Lehman Generator
var lcg = (function() {
// Set to values from http://en.wikipedia.org/wiki/Numerical_Recipes
// m is basically chosen to be large (as it is the max period)
// and for its relationships to a and c
var m = 4294967296,
// a - 1 should be divisible by m's prime factors
a = 1664525,
// c and m should be co-prime

requiring npm modules in the browser console

demo gif

The final result: require() any module on npm in your browser console with browserify

This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.

Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: mathisonian/requirify#5
