Thanks, that is the fairly straightforward -- but slow -- solution, which I have already implemented. I was asking if numpy had some filtering functions which might speed things up (it's a huge library, with which I'm not terribly familiar). It's fine if the answer is "no". _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org https://mail.scipy.org/mailman/listinfo/numpy-discussion
