The fundamental package needed for scientific computing with Python
is called NumPy. This package contains:

* a powerful N-dimensional array object sophisticated
* (broadcasting) functions tools for integrating C/C++ and
* Fortran code useful linear algebra, Fourier transform, and
* random number capabilities.

It derives from the old Numeric code base and can be
used as a replacement for Numeric. It also adds the
features introduced by numarray and can be used to
replace numarray.
