There's room for improvement here indeed. I need to check first whether fixing the comparison methods doesn't break anything. > I don't know, but maybe it would be better to raise an exception when > the index is a masked array then.

In the meantime, please just fill your masked array with the `filled` method or the corresponding function. Remmber that masked arrays are for convenience. As soon as you try to do some heavy computations, you're better processing data and mask yourself. _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
