I need to create a constraints set like the code shown below and give it an ID or index to the constraints names, then find the number of some rows and give them their respective value to load the constraint matrix.
glp_add_rows(lp,a*b);
for(int i=0; i<a; i++){
for(int j=0; j<b; j++){
glp_set_row_name(lp,i*a*b+j,"rest[i][j]"); //create some like "rest[i][j]"
}
}
glp_create_index(lp);
int ind[2];
ind[0]=glp_find_row(lp,rest[1][2]);
ind[1]=glp_find_row(lp,rest[2][3]);
int val[2]= 1, 1;
for(i=0; i<2; i++){
glp_set_mat_row(lp, i+1, int len, ind[i], val[i]);
}
