Scipy and NumPy Documentation

Python has modules several modules, Scipy and NumPy, that offer very similar functionality to the functions offered by Matlab. (This is not a conclusive list of math/science related Python modules, but this is a good place to start.)

N.B. I found that to use scipy.linalg.eig(A), I needed to say: import scipy; from scipy import linalg. That did the old tricking.
