I\'m learning the MATLAB language and would like to have some kind of free environment to experiment with. The MATLAB environment provided by MathWorks is commercial. There
I was recently enamoured of Python XY. It's not exactly like Matlab but it has many of the same functions and copies the look and feel. I would personally use it if I didn't want to buy a Matlab license though - not if I wanted to practice with a Matlab stand-in.
