Sets or returns the SIMatrix4 representation of the values of this transformation (the matrix is created automatically).

/*
This example demonstrates how to use the Matrix4 property to return the matrix representation
of the transformation as an SIMatrix4 (without having to explicitly create it first) as well as
how to set new values for the transformation using a 4x4 matrix.
