| class | gmres_tag |
| A tag for the solver GMRES. Used for supplying solver parameters and for dispatching the solve() function. More... | |
Namespaces | |
| namespace | viennacl |
Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them. | |
| namespace | viennacl::linalg |
Provides all linear algebra operations which are not covered by operator overloads. | |
| namespace | viennacl::linalg::detail |
Namespace holding implementation details for linear algebra routines. Usually not of interest for a library user. | |

| template<typename SRC_VECTOR , typename DEST_VECTOR > | |
| void | gmres_copy_helper (SRC_VECTOR const &src, DEST_VECTOR &dest, vcl_size_t len, vcl_size_t start=0) |
| template<typename ScalarType , typename DEST_VECTOR > | |
| void | gmres_copy_helper (viennacl::vector< ScalarType > const &src, DEST_VECTOR &dest, vcl_size_t len, vcl_size_t start=0) |
| template<typename VectorType , typename ScalarType > | |
| void | gmres_setup_householder_vector (VectorType const &input_vec, VectorType &hh_vec, ScalarType &beta, ScalarType &mu, vcl_size_t j) |
| Computes the householder vector 'hh_vec' which rotates 'input_vec' such that all entries below the j-th entry of 'v' become zero. | |
| template<typename VectorType , typename ScalarType > | |
| void | gmres_householder_reflect (VectorType &x, VectorType const &h, ScalarType beta) |
| template<typename MatrixType , typename VectorType , typename PreconditionerType > | |
| VectorType | solve (const MatrixType &matrix, VectorType const &rhs, gmres_tag const &tag, PreconditionerType const &precond) |
| Implementation of the GMRES solver. | |
| template<typename MatrixType , typename VectorType > | |
| VectorType | solve (const MatrixType &matrix, VectorType const &rhs, gmres_tag const &tag) |
| Convenience overload of the solve() function using GMRES. Per default, no preconditioner is used. | |
