I was about to send some mail myself about the non-zero problem. I
tracked it down in the numeric library and it looks like,
def nonzero(a):
"""Return the indices of the elements of a which are not zero, a
must be 1d
"""
return repeat(arange(len(a)), a)
should be:
def nonzero(a):
"""Return the indices of the elements of a which are not zero, a
must be 1d
"""
return repeat(arange(len(a)), nonZero(a))
At least that gives the behaviour I expect.
