Here is an example that does not work: from numpy import * vectors = array([arange(10), arange(10)]) # All x's, then all y's norms = apply_along_axis(linalg.norm, 0, vectors) # Now, what I was expecting would work: print vectors.T / norms # vectors.T has 10 elements, as d...

I see in the Python 3.1 documentation that this is fairly simple, but the facilities for doing this in 2.6 don't seem to be there.
