The simplistic current version choice is a copy. In my example, b is 1D, contiguous, with no 'C' or 'F' difference. Then that's possible to do an other choice, making a view. The reshape function is unpredictable and its behaviour is not documented. It cannot be used safely. Another remark against reshape: OWNDATA flag is False, even if b is a copy ! -- FP _______________________________________________ Numpy-discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
