Software Scientific Computing Support

http://www.scilab.org/
Scilab è un pacchetto di programmi grauiti per il calcolo numerico. Sviluppato in France by INRIA and ENPC, it is supported by major operating systems (Windows, Linux, MAC). Its syntax is very similar to Matlab, although the two programs are not fully compatible.
Recommended because: is a good alternative to MATLAB albeit with less help from video.


http://www.gnu.org/software/octave/
GNU Octave is a high-level language for numerical computations. Developed in the GNU project, is partially compatible with Matlab which is very reminiscent of the syntax. And 'cross-platform libraries and supports a variety of C.
Recommended because: other computing software Matlab that can work with gnuplot.


http://freemat.sourceforge.net/
FreeMat is a system of numerical analysis and cross-platform compatible with GNU Octave and Matlab, which remembers the syntax. It has the ability to interface with external pieces of code in C, C + + and Fortran.
Recommended because: third alternative to Matlab, states parties do not complete, but overall has a good feature.
