I may be missing something, but why not building it from scratch + a couple of elementary operations ? Is it too slow ? For example: # Assuming the lower part of a is zero before the operation a + a.T - np.diag(a.diagonal()) David _______________________________________________ Numpy-discussion mailing list [email protected] http://mail.scipy.org/mailman/listinfo/numpy-discussion
