mat(range(1,10)).T is a bit shorter, but I would agree that doing matrix
algebra in numpy is not as natural as with explicitly matrix-oriented
languages; my understanding is that this is due to numpy's broader
(n-dimensional) scope.

Numpy-masters: Is there a way to set a user- or project-specific config
switch or something like that to always get matrix results when dealing
with 1d and 2d arrays? I think that would make numpy much more
attractive for people like Stefan and me coming from the 2d world.
