Return a transformation that can place one set of vectors onto another while minimizing the least-squares distance between the corresponding points. The transformation is meant to be applied to the first set of coordinates. W. Kabsch (1978) A discussion of the solution for the best rotation to relate two sets of vectors. Acta Cryst.
