I like Todd's simple proposal: a.T2 should be equivalent to np.atleast_2d(arr).T

That means that a.T2.T2 doesn"t have the same shape as a. It boils down to practicality vs purity, as often ! _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org https://mail.scipy.org/mailman/listinfo/numpy-discussion
