Member Data Documentation

◆ l_strategy

template<typename ValueType = gko::default_precision, typename IndexType = gko::int32>
std::shared_ptr<typename matrix_type::strategy_type> gko::factorization::Ilu< ValueType, IndexType >::parameters_type::l_strategy { nullptr }

Strategy which will be used by the L matrix.

The default value nullptr will result in the strategy classical.

◆ skip_sorting

template<typename ValueType = gko::default_precision, typename IndexType = gko::int32>
bool gko::factorization::Ilu< ValueType, IndexType >::parameters_type::skip_sorting { false }

The system_matrix, which will be given to this factory, must be sorted (first by row, then by column) in order for the algorithm to work.

If it is known that the matrix will be sorted, this parameter can be set to true to skip the sorting (therefore, shortening the runtime). However, if it is unknown or if the matrix is known to be not sorted, it must remain false, otherwise, this factorization might be incorrect.

◆ u_strategy

template<typename ValueType = gko::default_precision, typename IndexType = gko::int32>
std::shared_ptr<typename matrix_type::strategy_type> gko::factorization::Ilu< ValueType, IndexType >::parameters_type::u_strategy { nullptr }

Strategy which will be used by the U matrix.

The default value nullptr will result in the strategy classical.
