matplotlib.mlab - Python for climatology, oceanograpy and atmospheric science

matplotlib.mlab

Numerical python functions written for compatibility with MATLAB commands with the same names. Most numerical python functions can be found in the numpy and scipy libraries. What remains here is code for performing spectral computations.
