Panagioti,
I certainly don't want to discourage you from learning Lisp, but I'm not
sure that rewriting numerical Maxima code by hand in Lisp will teach you
much. Working on symbolic computations in Lisp may be more educational and
productive.
Have you tried using mode_declare, compile, and arrays (rather than Maxima
lists and matrices) for your numerical code? With proper declarations and
use of arrays, compiled Maxima code should be almost as fast as hand-written
Lisp numerical code or even scalar Fortran code.
