I have two vectors that represent one point with respect to two different reference systems, eg, p0=[x0, y0, z0] and p1=[x1, y1, z1]; I need to know wich is the rotation matrix that transform the vector p1 to the vector p0. I absolutely don't know the angle rotation, neither the axis around wich the rotation is carried out.
I've tried to use 'vrrotvec' function and then 'vrrotvec2mat' to convert rotation from axis-angle to matrix representation; in theory, if I use this two functions to calculate the rotation matrix R between p1 and p0, when I compute R*p1 I should obtain p0, but the outcome is a vector different from p0.
I hope I've been clear!
Do you have any suggestion?
