It is GPLed, and is also an official part of the FSF GNU project.

substitute of S-plus, which is a statistical analysis program. There are a
list of other programs like that here:
(look in the right side-bar).
If you're looking for something to replace Matlab, you are better off with one
1. octave - http://www.octave.org/ - mostly compatible with Matlab. Still
2. scilab - http://scilabsoft.inria.fr/ - incompatible with Matlab, but
there's a program to convert Matlab programs to it (but not vice-versa).
Still incomplete in comparison to Matlab, but has a nice GUI interface.
It is sourceware, but I'm not sure if it's entirely free-as-in-speech. (albeit
the homepage links the word "Free" to the license) Its license is still
3. PDL (short for Perl Data Language) - http://pdl.perl.org/
A package offering fast and compact tensor manipulation operations to Perl,
similar to those provided by Matlab. Still incomplete.
There may be other packages like that, but I haven't had any experience with
them, so STFW. I don't think there's anything quite like Matlab available yet
as far as the availability of modules and add-ons is concerned. But if I
understand Tzahi's needs, then he should be able to find something sufficient
for them, that is open-source.
