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
