Hi,
I wanted to add an elementwise divide operations for ublas matrices using operator /
I don't think that's such a great idea. Using regular operators for elementwise operations is likely to be surprising. i.e. if you can do (A / B) you should be able to do (A * B) as well, and it you be the inverse of A / B. But multiplication is defined for matrices and is *not* an elementwise operation. There is no way to define this that won't surprise someone. There's a good reason why uBlas doesn't provide these operators already and why MATLAB has a separate set of operators for elementwise operations.
So here's the patch I would like to be applied to ublas. As I said, it's almost trivial and would allow to add matrix-matrix operator/ for those who want it. Is it possible to have that added to ublas?
Better off creating a ticket and attaching the patch. - Jeff
