Empty input to an algorithm can often be handled naturally by empty matrices in the implementation. Quite often I find that if I've coded things right, the boundary empty input case is handled naturally in this way. I would prefer that no functions crashed when passed empty matrices. Just my 2 cents, John. _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
