Using a larger integer type for the indices is not supported in Scipy at the moment. It's possible to implement, but needs someone to still do a bit of work: http://projects.scipy.org/scipy/ticket/1307 _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
