I'm pretty sure checking the existence of a solution to a linear Diophantine equation is cheap, but I guess figuring out whether it falls within the "shape" bounds is less obvious... -- Nathaniel _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
