Of course. That's where all the overhead that I mentioned is created, directly or indirectly. So, the aim is to replace the .new_matrix() code by something faster. I partially succeeded (see #8611 [merged] and #10763 [needs review]), but one bottle neck remains. > It does not currently > make an "empty" matrix, but defaults to a zero matrix. Sure. And the question is whether there really is no faster way to create a zero matrix, than to *copy* a zero matrix (this is what is currently done in the dense case). Perhaps it is naive, but I thought that writing should be faster than reading and writing.
