Next time, please start a new post. This apparently doesn't have anything to do with the thread you appended to.

So, Shadow Matrix in what context?

Depends on the application and the shadowing technique being discussed. But commonly it is a term used in shadow mapping for a transform that maps from object-space, world-space, or camera-eye-space coordinates to a light-NDC-space (mapped to 0..1). However in planar-projected shadows, it's a matrix that smashes 3D geometry onto a plane.
