Detailed Description

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

imbalance_bounded_limit is a strategy_type which decides the number of stored elements per row of the ell part. It uses the imbalance_limit and adds the upper bound of the number of ell's cols by the number of rows.
