What do you get, if not the expected value? And are the calls to atleast_1d, np.array, etc., necessary to trigger the problem, or will just plain a.max(0) do it? -- Nathaniel _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
