Detailed Description

template<typename ValueType = default_precision, typename IndexType = int32>
class gko::matrix::Hybrid< ValueType, IndexType >::column_limit

column_limit is a strategy_type which decides the number of stored elements per row of the ell part by specifying the number of columns.

Constructor & Destructor Documentation

column_limit()

template<typename ValueType = default_precision, typename IndexType = int32>

gko::matrix::Hybrid< ValueType, IndexType >::column_limit::column_limit ( size_type  num_column = 0 )

inlineexplicit

Creates a column_limit strategy.

Parameters

num_column

the specified number of columns of the ell part

Member Function Documentation

compute_ell_num_stored_elements_per_row()

template<typename ValueType = default_precision, typename IndexType = int32>

size_type gko::matrix::Hybrid< ValueType, IndexType >::column_limit::compute_ell_num_stored_elements_per_row ( array< size_type > *  row_nnz ) const

inlineoverridevirtual
