This subject can get quite complicated. How exactly are you interpolating rotations with matrices in Maya? From a matrix, you have to extract the rotation matrix, then either convert it to euler rotations or quaternions before doing any kind of interpolation.
Just calculate the rotations using the euler rotations using lerp. It's the fastest way to get any kind of interpolation. If you're animating through the different rotations and you need a smooth interpolation, consider looking into quaternion slerp or quaternional nlerp.
