Well, I actually wrote this code long before I was aware even of scipy :)

But you're right, I didn't know about those.  Still, my little frange is 
useful when I don't want to load all of scipy but just need Numeric + a few 
simple utilities for plotting or testing things.

Thanks for the pointer, though.  As time goes by, I'm converting more and more 
of my daily use to scipy...

Best,
