Is this case it amounts to the same because you multiply it to an
object that has compile time sizes, but it general it's better to
specify the sizes at compile time when you can.

Your code will look much simpler by using an Isometry3d and a Rotation2D:

- rot = Rotation2Dd(theta);
- Isometry3d::inverse() does exactly what you wrote;
- Isometry3d are compatible with 3D vectors;
- Isometry3d has .linear() and .translation() members for easy
read-write access;
