[Numpy-discussion] matrices in 1.1
Fri Mar 21 14:00:25 CDT 2008
But asmatrix returns a matrix object and any subsequent operation of it returns a matrix. What I am thinking about is a convenient way to apply matrix operation on an array.
BTW, A matrix is just a rank 2 tensor, so matrix (tensor) algebra can be applied to an arbitrary rank tensor, for example APL's . operator.

Use ``asmatrix``. (Does not copy.)
After that the only needed "unification" I have
encountered is that iteration over a matrix should
return arrays (not matrices). I believe this is
under consideration for 1.1.
