numpy.ma uses np.seterr(divide='ignore', invalid='ignore') for most of its operations, so it is overriding your settings. This is usually desirable since many of the masked values will be trip these errors spuriously even though they will be masked out in the result. -- Robert Kern _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
