It looks like this is exactly what I was trying to do (learn). The symbolic versions really help show what is going on in the derivations sub-package by showing how each of the 9 matrix elements are found. I'll try to hack it to use active rotations. -- Seb _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org https://mail.scipy.org/mailman/listinfo/numpy-discussion
