Great matlab alternative. Just beware that not all scripts created with Matlab if that is what you are using it for.
i agree with m4daredsun. octave is a nice matlab-clone, almost (!) as good as the original. however, python + matplotlib + spyder is an open source concept that in many aspects already outruns matlab.
Not bad but I prefer [python + numpy + scipy + matplotlib] for scientific/technical computing and data processing
es muy funcional y liviano, buena opcion para evitar trabajar con el pesado matlab
