    • Method Detail

      • getR

        DoubleMatrix getR()
        Returns the matrix $\mathbf{R}$ of the decomposition.

        $\mathbf{R}$ is an upper-triangular matrix.

        Returns:
        the $\mathbf{R}$ matrix
      • getQ

        DoubleMatrix getQ()
        Returns the matrix $\mathbf{Q}$ of the decomposition.

        $\mathbf{Q}$ is an orthogonal matrix.

        Returns:
        the $\mathbf{Q}$ matrix
      • getQT

        DoubleMatrix getQT()
        Returns the transpose of the matrix $\mathbf{Q}$ of the decomposition.

        $\mathbf{Q}$ is an orthogonal matrix.

        Returns:
        the $\mathbf{Q}$ matrix
