gt;--- I believe the matrices `euler_mat' and `euler_comp_mat' should be the same, but they aren't, so it's unclear to me what particular composition is meant to produce the matrix specified by this Z1Y2X3 transformation. What am I missing? -- Seb ___

is made of. However, I cannot reproduce this matrix via composition; i.e. by multiplying the underlying rotation matrices. Any tips would be appreciated. -- Seb ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org https://mail.scipy.org/mailman/listinfo/numpy-discussion

kage. 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 __
