[PyMOL] Algorithm to Rotate One Set of Vectors onto Another

[Buz Barstow]

Dear All,

I'm looking for an algorithm that will allow me to derive a  
transformation matrix that superimposes one set of orthogonal vectors  
onto another set of orthogonal vectors, that I can then use to  
transform another set of orthogonal vectors.

Thanks! and all the best,
