I know that the computedRotationMatix is calculated multiplying PreRotation * Rotation * PostRotation;

computedRotationMatix = PreRotation * Rotation * PostRotation;

But currently i only knows the computedRotationMatix , PreRotation , PostRotation;

How can i find the Rotation matrix?

Thanks for your time

Provided that PreRotation and PostRotation are invertible,

Rotation = PreRotation[sup]-1[/sup] * computedRotationMatrix * PostRotation[sup]-1[/sup]

And provided they are rotations, you can transpose them instead of finding their inverses, since the results should match.
