[Numpy-discussion] array vs matrix
Sat Jun 7 14:37:02 CDT 2008
what is the current plan with array and matrix with regard of calculating
? I.e. elementwise vs sin(A) = Q*sin(D)*Q^T? Is the current approach
(elementwise for array and Q*sin(D)*Q^T for matrix) the way to go?
We are solving the same problem in SymPy:
so I'd like to have the exact same behavior as numpy has, so that we
are compatible. But I was wondering if the current status is ok, or if
many numpy developers (or users?) would like this to be changed.
I think a clean solution is to treat matrices as mathematical objects,
i.e. A*B and sin(A) being matrix multiplication and matrix sin
respectively, while leaving the array for elementwise operations.
But above all, I'd like to be compatible with numpy, otherwise it will
be a mess.
Thanks for any feedback,
