scipy

I recently do a lot of mathematical computation, using MATLAB, unfortunately MATLAB is not open-source and fairly expensive to buy. There is a open-source reimplementation of the MATLAB language called GNU Octave. But I never really liked it, mostly because of the missing visualization features compared to MATLAB. So I started to look for something else, and as I’m a huge fan of Python it was obvious to take a look at SciPy, a Scientific extension based on NumPy, a highly optimized multi-dimensional array library.
