print_duals

Prints the values of the duals of the lp.

void print_duals(lprec *lp);

Return Value

print_duals has no return value.

Parameters

lp

Pointer to previously created lp model. See return value of make_lp, read_lp, read_LP, read_lpt, read_LPT, read_mps, read_freemps, read_MPS, read_freeMPS, read_XLI

Remarks

The print_duals function prints the values of the duals of the lp. This can only be done after a successful solve.
This function is meant for debugging purposes. By default, the output is stdout. However this can be changed via a call to set_outputstream, set_outputfile.

Example

#include <stdio.h>
#include <stdlib.h>
#include "lp_lib.h"

int main(void)
{
  lprec *lp;

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

  solve(lp);

  print_duals(lp, 1);

  delete_lp(lp);

  return(0);
}
