Mathematica vs Matlab vs Python
The Python code there is not very idiomatic Numpy code. It's written for Numeric, and fancy indexing etc. are not used. Seems like the author also left it as an exercise for the reader to implement the data file parser in Matlab. I doubt it can be easily done in 20 lines :) -- Pauli Virtanen

Yup. It's not even very idiomatic Python. readlines() is probably a bad idea unless your file is trivial length, and even ignoring numpy.loadtxt(), all of this could be considerably simplified with the built-in csv module. David

or a 1-liner with scipy.io.loadmat ...
No crack! Some dude built a matlab reader for Python. Crazy man! Gaël

Not even a Frenchman would be that crazy. Must've been a Brit...
