[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 ___ NumPy-Discussion
