You can generate random integers between 0 and 10, and divide them by 10: np.random.random_integers(0, 10, (5, 5)) / 10. > - Only the rows where the sum is 1 must be kept I'm not sure I understand the exact structure you describe. Perhaps an example would help. Stéfan _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
