PyMatrix is available for test and review.
http://www3.sympatico.ca/cjw
PyMatrix provides access to basic matrix arithmetic, using Python and
numarray.
Examples:
A * B => the product of
matrices A and B
A.I => the inverse of matrix A
A.EVectors => the eigenvectors of A
A.var(0) => the variances of the
columns of A
(a.T*a).I * a.T*b => the solution (x) for a *
x = b,
where a is a
matrix and b a column vector
This package was developed on a Windows XP. I would appreciate
comments, particularly with respect to usage on other systems.
