Namespaces | |
| viennacl | |
| Main namespace in ViennaCL. Holds all the basic types such as vector, matrix, etc. and defines operations upon them. | |
| viennacl::linalg | |
| Provides all linear algebra operations which are not covered by operator overloads. | |
| viennacl::linalg::detail | |
| Namespace holding implementation details for linear algebra routines. Usually not of interest for a library user. | |
Functions | |
| template<typename IndexT , typename NumericT > | |
| IndexT | viennacl::linalg::detail::merge_subtract_sparse_rows (IndexT const *w_coords, NumericT const *w_elements, IndexT w_size, IndexT const *u_coords, NumericT const *u_elements, IndexT u_size, NumericT alpha, IndexT *z_coords, NumericT *z_elements) |
| Subtracts a scaled sparse vector u from a sparse vector w and writes the output to z: z = w - alpha * u. More... | |
| template<typename SizeT , typename NumericT > | |
| void | viennacl::linalg::detail::insert_with_value_sort (std::vector< std::pair< SizeT, NumericT > > &map, SizeT index, NumericT value) |
