| Name | Description |
|---|---|
lu(const ComplexMatrix A) -> Object | Computes the LU decomposition of a ComplexMatrix A.. By default, partial pivoting is used and the resulting factorization is PA = LU, where P is a permutation matrix, L is lower triangular with unit diagonal elements, and U is upper triangular. To use full pivoting instead, provide the option 'pivoting' with value 'full'. The resulting factorization is PAQ = LU, where P and Q are permutation matrices. |
lu(const RealMatrix A) -> Object | Computes the LU decomposition of a RealMatrix A.. By default, partial pivoting is used and the resulting factorization is PA = LU, where P is a permutation matrix, L is lower triangular with unit diagonal elements, and U is upper triangular. To use full pivoting instead, provide the option 'pivoting' with value 'full'. The resulting factorization is PAQ = LU, where P and Q are permutation matrices. |
lu(const ComplexMatrix A, const Map options) -> Object | Computes the LU decomposition of a ComplexMatrix A. |
lu(const RealMatrix A, const Map options) -> Object | Computes the LU decomposition of a RealMatrix A. |
