[PyMOL] euler-rod axis

hi, from the get_object_matrix output, i can use the euler-rodrigues transformation http://en.wikipedia.org/wiki/Euler%E2%80%93Rodrigues_formula and get the axis and angle of rotation. is there a way to place the axis? perhaps from the translation vector in the matrix? thanks jpd-
