Glpk includes some internal routines for such purpose (see glpspm.c), in particular, spm_show_mat to write the sparse matrix pattern in bitmap format. However, I do not know if it is reasonable to carry out such routines on api level. _______________________________________________ Help-glpk mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-glpk
