You should also read the first chapters of the book "Guide to NumPy" 
which are available on-line for immediate download.  There is a 
comprehensive description of the differences between Numeric and NumPy 
as well as tips for compatibility.

You must also import numpy.oldnumeric before it is available.

import numpy.oldnumeric

numpy.oldnumeric.mlab

You will notice that the module is simple a re-naming module.  All of 
the functionality is in numpy but under possibly different names.

All functions in Numeric are available in NumPy (as far as I know).  If 
you encounter a situation where that is not true, please let me know.
