Function Dune::XT::LA::solve_qr_factorized

template<class MatrixType, class VectorType, class SecondVectorType, class RhsVectorType, class IndexVectorType>
void Dune::XT::LA::solve_qr_factorized(const MatrixType &QR, const VectorType &tau, const IndexVectorType &permutations, SecondVectorType &x, const RhsVectorType &b, SecondVectorType *work = nullptr)

Solves Ax = b, where AP = QR is the QR decomposition. QR has to be stored in QR and tau, P has to be stored in permutations.
