google for: Numpy, Scipy, weave, f2py, numarray

scipy is the grand wrapper which will give you on top of Numeric/Numarray (the
array library proper) a ton of other stuff: special functions, numerical
methods, fortran code wrapping, and out-of-the box wrappers to most/all of blas
and lapack.

For plotting/visualization (which you'll eventually need), matplotlib,
gnuplot.py and MayaVi should be on your list.

For PostScript/LaTeX algorithmic generation, PyX is an amazing tool.
