In general, baking matrices simply means multiplying them ahead of time. Traditional scene graphs are one example of baking, where each node contains a transformation matrix from its parent, and also a full world transformation matrix. When rendering, instead of multiplying all the matrices each frame, the full world transformation is used. If a node's local matrix changes, the change is propagated to its children and the matrices are recalculated. This saves computation at the expense of memory use.
