numpy.linalg.inv does solve(a, identity(a.shape[0], dtype=a.dtype)) It doesn't use xGETRI since that's not included in lapack_lite. numpy.linalg.pinv OTOH does use SVD, but that's probably more costly. -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
