I presume what you did was something like this: from matplotlib import pylab [N,x] = hist(eig, 10) What you actually want is this: from matplotlib import pylab [N,x] = pylab.hist(eig, 10) Or, if you're at the interactive prompt (but remember that it is inadvisable to do so in modules): from matplotlib.pylab import * [N,x] = hist(eig, 10) You will probably want to review the section of the tutorial on importing modules if you don't understand the differences. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
