| Purpose |
|
|
Copy the right-hand-side values into an array.
|
|
| Synopsis |
|
|
int QSget_rhs (QSprob p, double *rhs)
|
|
| Arguments |
|
p |
|
a handle to an initialized problem. |
rhs |
|
returns the right-hand-side values as an array; this field should point to an array of length at least nrows, the number of rows in the problem. |
|
|
| Returns |
|
|
A zero value if the function terminated correctly, and a non-zero value if an error occurred.
|
|
| Description |
|
|
This function returns the right-hand-side values of the constraints (the b values in the linear system Ax = b) as a dense vector, that is, all coefficients (both zero and non-zero) are returned in the array rhs. The calling function must allocate the memory for the rhs array; it should be of length at least nrows, the number of rows in the problem.

| Example |
|
|
/* p is an initialized QSprob, a handle to an existing LP problem */
int rval, nrows;
double *rhs;
nrows = QSget_rowcount (p);
rhs = (double *) malloc (nrows * sizeof (double));
rval = QSget_rhs (p, rhs);
if (rval) {
fprintf (stderr,
"Could not get right-hand-side, error code %d\n", rval);
} else {
printf ("Right-Hand-Side\n");
for (i = 0; i < nrows; i++) {
printf ("%f\n", rhs[i]);
}
}
free (rhs);
