[Numpy-discussion] Mirror/flip numpy array?
Hello list, I have a really simple newbie question: How can I mirror/flip a numpy.ndarray? I.e. mirror switches the colums (leftmost becomes rightmost and so on), flip changes the rows (top becomes bottom and so on)?

The last line of these functions are return m[:, ::-1] and return m[::-1,...], respectively. ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
