matplotlib::pylab Namespace Reference


Detailed Description

This is a matlab(TM) style interface to matplotlib.

The following plotting commands are provided; some of these do not
exist in matlab(TM) but have proven themselves to be useful nonetheless.
The majority of them, however, have matlab analogs

Most of the other commands are from Numeric, MLab and FFT, with the
exception of those in mlab.py provided by matplotlib.
