Maybe take a look at the algorithms in this paper:

Alternatively, it might be good to have matrix exponent/logarithms for doing simple interpolations whenever, since exp((1-t) * log(A) + t * log(B)) is a pretty simple/effective interpolation strategy.

There are also geodesic methods, though they are more sophisticated.

The math is a bit over my head. Added you as a collaborator, PRs welcome. :ok_hand:
