That's the formula for applying a rotation in the reference frame of 
another rotation.

Do you know anything more about these matrices than that they are 
matrices? Are they supposed to contain no scale? No translation? If you 
can formulate them as quaternions, writing out the analytical answer is 
a lot simpler :-)
