# set_rh_vec, str_set_rh_vec Set the right hand side (RHS) vector (column 0). void set_rh_vec(lprec *lp, REAL *rh); unsigned char str_set_rh_vec(lprec *lp, char *rh_string); Return Value set_rh_vec has no return value. str_set_rh_vec returns TRUE (1) if the operation was successful. A return value of FALSE (0) indicates an error. Parameters lp Pointer to previously created lp model. See return value of make_lp, copy_lp, read_lp, read_LP, read_mps, read_freemps, read_MPS, read_freeMPS, read_XLI rh An array with row elements that contains the values of the RHS. rh_string A string with row elements that contains the values of the RHS. Each element must be separated by space(s). Remarks The set_rh_vec, str_set_rh_vec functions set all values of the RHS vector (column 0) at once. Note that element 0 of the array is not considered (i.e. ignored). Row 1 is element 1, row 2 is element 2, ... If the initial value of the objective function must also be set, use set_rh. Example
    #include <stdio.h>
    #include <stdlib.h>
    #include "lp_lib.h"

    int main(void)
    {
      lprec *lp;
      REAL rhs[1+2]; /* must be 1 more then number of rows ! */

      /* Create a new LP model */
      lp = make_lp(2, 0);
      if(lp == NULL) {
        fprintf(stderr, "Unable to create new LP model\n");
        return(1);
      }

      rhs[1] = 1.0;
      rhs[2] = 2.0;
      set_rh_vec(lp, rhs);

      delete_lp(lp);
      return(0);
