<h1>set_rh_vec, str_set_rh_vec</h1>
<p>
Set the right hand side (RHS) vector (column 0).</p>
<p>
<b>void set_rh_vec(lprec </b>*<i>lp</i><b>, REAL </b>*<i>rh</i><b>);</b></p>
<p>
<b>unsigned char str_set_rh_vec(lprec </b>*<i>lp</i><b>, char </b>*<i>rh_string</i><b>);</b></p>
<p class="label">
<b>Return Value</b></p>
<p>
<b>set_rh_vec</b> has no return value. <b>str_set_rh_vec</b> returns TRUE (1)
if the operation was successful. A return value of FALSE (0) indicates an
error.
</p>
<p class="label">
<b>Parameters</b></p>
<p class="dt">
<i>lp</i></p>
<p class="indent">
Pointer to previously created lp model. See return value of <A HREF="make_lp.htm">make_lp</A>, <A HREF="copy_lp.htm">copy_lp</A>,
<A HREF="read_lp.htm">read_lp,
read_LP</A>, <A HREF="read_mps.htm">read_mps, read_freemps, read_MPS, read_freeMPS</A>, <A HREF="read_XLI.htm">read_XLI</A></p>
<p class="dt">
<i>rh</i></p>
<p class="indent">
An array with row elements that contains the values of the RHS.</p>
<p class="dt">
<i>rh_string</i></p>
<p class="indent">
A string with row elements that contains the values of the RHS. Each element
must be separated by space(s).</p>
<p class="label">
<b>Remarks</b></p>
<p>
The <b>set_rh_vec</b>, <b>str_set_rh_vec</b> functions set all values of the
RHS vector (column 0) at once.<br>
Note that element 0 of the array is not considered (i.e. ignored). Row 1 is
element 1, row 2 is element 2, ...<br>
If the initial value of the objective function must also be set, use <A HREF="set_rh.htm">
set_rh</A>.
</p>
<p class="label">
<b>Example</b></p>
<pre><code>#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);
