figure(), show(), etc. are pylab (or matplotlib.pyplot) functions, not matplotlib functions. Especially for a long program, it is strongly recommended that you not use "from numpy import *". The recommended form is import numpy as np import matplotlib.pyplot as plt It will help you keep a clear picture of where various types of functionality are coming from. See also http://matplotlib.sourceforge.net/faq/usage_faq.html and note that a primarily object-oriented approach is recommended for use in other than quick scripts and interactive plotting.
