Finding a rotation matrix with given origin and rotated matrices

[faribataghavi]

Hi,

I have two diagonal matrixes (rotated and origin), how can I calculate the rotation matrix between these two matrices?

I have to mention that this rotation matrix should be a representation of successive rotation around z, y and again z axes:
R(zyz)=R(z)R(y)R(z)

The information that I have is just two diagonal matrices.

Thank You so much for helping me
