Detailed Description

template<typename ValueType = default_precision, typename IndexType = int32>
struct gko::matrix::Csr< ValueType, IndexType >::permuting_reuse_info

A struct describing a transformation of the matrix that reorders the values of the matrix into the transformed matrix.

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

void gko::matrix::Csr< ValueType, IndexType >::permuting_reuse_info::update_values	(	ptr_param< const Csr >	input,
		ptr_param< Csr >	output
	)		const

Propagates the values from an input matrix to the transformed matrix.

The output matrix needs to have been computed using the transformation that was also used to generate this reuse data. Internally, this permutes the input value vector into the output value vector.
