This class generates the (S)SOR preconditioner.
The SOR preconditioner starts from a splitting of the the matrix
A detailed description can be found in Iterative Methods for Sparse Linear Systems (Y. Saad) ch. 4.1.
This class is a factory, which will only generate the preconditioner. The resulting LinOp will represent the application of
ValueType | The value type of the internally used CSR matrix |
IndexType | The index type of the internally used CSR matrix |
std::unique_ptr< composition_type > gko::preconditioner::Sor< ValueType, IndexType >::generate | ( | std::shared_ptr< const LinOp > | system_matrix | ) | const |
Creates a new product from the given components.
The method will create an ComponentsType object from the arguments of this method, and pass it to the generate_impl() function which will create a new AbstractProductType.
Args | types of arguments passed to the constructor of ComponentsType |
args | arguments passed to the constructor of ComponentsType |
