The most useful feature in r2 for working with data structures is pf commands, which prints formatted data. You can use this command to print data in certain address according to a defined format, and moreover - define specific formats, for repeating structure. The command is used as pf [types] [member1] [member2] [...]. To see all the type code, pf??, and pf??? for some usage examples. To define a type, use pf.[type] [..]. Example:

[0x08048e26]> pf.node ii*? value index (node)next
[0x08048e26]> pf.node @@ obj.node*
 value : 0x0804b230 = 432
 index : 0x0804b234 = 6
 next : (*0x0) NULL

	I got problems installing Matlab R2022a on Arch. Running the installer throws the following error:

	```
	terminate called after throwing an instance of 'std::runtime_error'
	what(): Failed to launch web window with error: Unable to launch the MATLABWindow application. The exit code was: 127
	fish: Job 1, 'sudo ./install' terminated by signal SIGABRT (Abort)
	```

	I fixed it by running the following commands.

	Dalvik bytecode has two main type classes, primitive types and reference types. Reference types are objects and arrays, everything else is primitive.
