qr(const RealMatrix A) -> Object | Computes the QR decomposition of a RealMatrix A.. By default, no pivoting is used and the resulting factorization is A = QR, where Q is a unitary matrix and R is upper triangular. To use partial (column) pivoting, provide the option 'pivoting' with value 'partial'. The resulting factorization is AP = QR, where P is a permutation matrix. To use full pivoting, provide the option 'pivoting' with value 'full'. |
qr(const ComplexMatrix A) -> Object | Computes the QR decomposition of a ComplexMatrix A.. By default, no pivoting is used and the resulting factorization is A = QR, where Q is a unitary matrix and R is upper triangular. To use partial (column) pivoting, provide the option 'pivoting' with value 'partial'. The resulting factorization is AP = QR, where P is a permutation matrix. To use full pivoting, provide the option 'pivoting' with value 'full'. |
qr(const ComplexMatrix A, const Map options) -> Object | Computes the QR decomposition of a ComplexMatrix A. |
qr(const RealMatrix A, const Map options) -> Object | Computes the QR decomposition of a RealMatrix A. |
