In glpk the constraint matrix is stored in sparse format. There exists some api function to construct the constraint matrix: glp_add_rows/glp_add_cols add rows/columns to the constraint matrix glp_set_mat_row/glp_set_mat_col set a row/column of the constraint matrix to a given sparse vector glp_load_mat loads the whole constraint matrix in sparse format.
