> 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.
