I want to get the inverse of this homogeneous transformation matrix: iab = { {1, 0, 0, 0}, {0, 0, -1, 0}, {0, 1, 0, 3}, {0, 0, 0, 1} } using the inverse function, but the problem is that … TranslationTransform and RotationTransform to compute the inverse, but the problem with that approach is that I can only create a rotation matrix or a translation matrix, but not both in one transformation like in the above matrix I posted. …
