How to get a partial transform matrix from an existing one

When rotating or moving an object using transformation matrices, in some cases we need to be able to extract a part of it from the entire rotation/movement. For example, when rotating an object by 180 degrees, we need to rotate it not at once, but in several steps, each time rotating it by 30 degrees. Linear interpolation of matrices can help us with this.
