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.
