Detailed Description

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

ELL is a matrix format where stride with explicit zeros is used such that all rows have the same number of stored elements. The number of elements stored in each row is the largest number of nonzero elements in any of the rows (obtainable through get_num_stored_elements_per_row() method). This removes the need of a row pointer like in the CSR format, and allows for SIMD processing of the distinct rows. For efficient processing, the nonzero elements and the corresponding column indices are stored in column-major fashion. The columns are padded to the length by user-defined stride parameter whose default value is the number of rows of the matrix.

This implementation uses the column index value invalid_index<IndexType>() to mark padding entries that are not part of the sparsity pattern.

Template Parameters

ValueType	precision of matrix elements
IndexType	precision of matrix indexes

◆ Ell() [1/2]

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

gko::matrix::Ell< ValueType, IndexType >::Ell ( const Ell< ValueType, IndexType > & )

Copy-constructs an Ell matrix. Inherits executor and dimensions, but copies data without padding.

◆ Ell() [2/2]

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

gko::matrix::Ell< ValueType, IndexType >::Ell ( Ell< ValueType, IndexType > && )

Move-constructs an Ell matrix. Inherits executor, dimensions and data with padding. The moved-from object is empty (0x0 with empty Array).

Parameters

row	the row of the requested element
