Cython doesn't vectorize the slice operations such as b[:,j-g] but falls back to Numpy on them. You'll need to convert the slice notation to a loop to get speed gains. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
