Unfortunately, I'm in something of a bind with version. Although, I wonder if I can operate two versions of Python on the same Win XP? Whoops, I read that wrong. Yes, I think I can upgrade numpy without much difficulty. I am stuck with holding on the current version of Python. Robert Kern wrot

[Numpy-discussion] nicest way to apply an arbitrary sequence of row deltas to an array

2009-12-20 Thread George Dahl
Hi everyone, I was wondering if anyone had insight on the best way to solve the following problem. Suppose I have a numpy array called U. U has shape (N,M) Suppose further that I have another array called dU and that dU has shape (P,M) and that P has no particular relationship to N, it could be la
