Public Member Functions
void	swap_clear ()
	Clears all swap vectors (swapk, swapr, all_swaps).
void	col_clear ()
	Clears all col vectors (col_k, col_r, col_k_nnzs, col_r_nnzs).
void	row_clear ()
	Clears all row vectors (row_k, row_r).

Public Attributes
vector< idx_it >	swapk
	List of indices from row r that will be swapped to row k.
vector< idx_it >	swapr
	List of indices from row k that will be swapped to row r.
idx_vector_type	all_swaps
	Column indices of all swaps done in swapk and swapr.
idx_vector_type	col_k_nnzs
	Row indices of non-zeros in the new column k.
idx_vector_type	col_r_nnzs
	Row indices of non-zeros in the new column r.
elt_vector_type	col_k
	Non-zero values in the new column k (order dependent on col_k_nnzs).
elt_vector_type	col_r
	Non-zero values in the new column r (order dependent on col_r_nnzs).
idx_vector_type	row_k
	Column indices of non-zeros in the new row k.
idx_vector_type	row_r
	Column indices of non-zeros in the new row r.

Detailed Description

template<class el_type>
class swap_struct< el_type >

A structure containing variables used in pivoting a LIL-C matrix.

Storing these variables in a combined structure reduces memory requirements and bundles together all temporary structures needed during pivoting.
