Use the statement 'from pylab import *' in the beginning of your program. Others, of course, may find it more tasteful and Pythonic to do: [N,x]=pylab.hist(eig, 10) i.e., prefix it with the package name. Wouldn't want to clutter the global namespace of your program after all. Good luck with it then. I think I see a reference to advanced linear algebra with 'eig' (Eigen-?) and I'm sure you understand that better than I. :) -- Theerasak -- http://mail.python.org/mailman/listinfo/python-list
