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. :)
