EulerInverse
2D/3D• EulerInverse[epars] returns a list of two (2D) or four (3D) Euler parameters corresponding to the inverse of the rotation represented by epars. The function of EulerInverse is analogous to the inversion of a rotation matrix. • EulerInverse simply negates all terms but the first in the list of Euler parameters.
• See also: EulerMultiply, EulerParameters. Further Examples Load the Modeler3D package. Here are a pair of arbitrary rotations about arbitrary axes. They can be converted to Euler parameters or rotation matrices and multiplied, and then converted back to rotations with the same result.

However, multiplying Euler parameters is computationally inexpensive.

The inversion of a rotation matrix (which is equivalent to transposing the matrix) is analogous to negating all but the first Euler parameter.
