What if you made objects i, j, etc. such that i*j = (0, 1) and etcetera? Maybe you could generate them with something like (i, j, k) = einstein((1, 2, 3)) . Feel free to disregard me since I haven't really thought too hard about things and might not even really understand what the problem is *anyway*. I'm just trying to help brainstorm. :) --Josh _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
