        public boolean decompose​(org.ejml.data.DMatrixRMaj orig)

        This implementation of LU Decomposition uses the algorithm specified below: "Numerical Recipes The Art of Scientific Computing", Third Edition, Pages 48-55

        Parameters:
        orig - The matrix that is to be decomposed. Not modified.
        Returns:
        true If the matrix can be decomposed and false if it can not. It can return true and still be singular.
