Constructor Detail

### QL

    public QL(int m,
              int n)

  Constructs an empty QL decomposition

  Parameters:
    `m` - Number of rows. Must be larger than or equal the number of columns
    `n` - Number of columns

Method Detail

### factorize

    public static QL factorize(Matrix A)

  Convenience method to compute a QL decomposition

  Parameters:
    `A` - Matrix to decompose. Not modified
  Returns:
    Newly allocated decomposition

### factor

    public QL factor(DenseMatrix A)

  Computes an orthogonal decomposition

  Parameters:
    `A` - Matrix to decompose. Overwritten on exit. Pass a copy to avoid this
  Returns:
    The current decomposition

### getL

    public LowerTriangDenseMatrix getL()

  Returns the lower triangular factor

### getQ

    public DenseMatrix getQ()

  Returns the orthogonal part of the factorization
