[Numpy-discussion] swaxes(0, 1) 10% faster than transpose on 2D matrix?

Hello List,

I noticed that swapaxes(0,1) is consistently (on my system) 10% faster than
transpose on a 2D matrix.

Any reason why? Any reason why the swapaxes algorithm is not used in
transpose?

Just wondering. Thanks,

Mark
