Hello everyone！ I have questions about the function MNE. Transforms. _ find _ vector _ rotation. Why is it divided by S instead of the square of S?This link # linear algebra - Calculate Rotation Matrix to align Vector $A$ to Vector $B$ in $3D$? - Mathematics Stack Exchange, it seems to be divided by the square of S.
What is this derivation process, from the standard Rodrigues’ rotation formula to the present formula ( this link # linear algebra - Calculate Rotation Matrix to align Vector $A$ to Vector $B$ in $3D$? - Mathematics Stack Exchange)
