same API as numarray, but not exactly, so if somethign doesn't appear to be
working as the book suggests, make sure to check out the current numpy docs.

Note that there seems to be a new addition of the book:

Numerical Methods in Engineering with Python 3

I assume it uses a recent numpy version. (too bad there isn't a py2, recent
numpy version, but there you go...)
