EGdMatrix_t Struct Reference

Detailed Description

structure to hold a dense matrix, we choose a row representation of the matrix, and we allow row and column permutations. All actual values in the matrix are stored in EGdMatrix_t::matval, and the rows in EGdMatrix_t::matrow.

Examples:

eg_dmatrix.ex.c.

Definition at line 55 of file eg_dmatrix.h.

Data Fields
int *	col_ord
	Array of size at least EGdMatrix_t::col_sz containing the order ammong all columns i.e. it is a permutation of {0,....,col_sz-1} which is how the matrix is treated internally.
size_t	col_sz
	Number of columns in the matrix.
EGlpNum_t **	matrow
	Array of size EGdMatrix_t::row_sz containing all rows of the matrix.
EGlpNum_t *	matval
	Values for all entries.
int *	row_ord
	Array of size at least EGdMatrix_t::row_sz containing the order ammong all rows, i.e. it is a permutation of {0,...,row_sz-1} which is how the matrix is treated internally.
size_t	row_sz
	Number of rows in the matrix.
