| Purpose |
|
|
Delete a set of rows from the problem.
|
|
| Synopsis |
|
|
int QSdelete_rows (QSprob p, int num, int *dellist)
|
|
| Arguments |
|
p |
|
a handle to an initialized problem. |
num |
|
the number of rows to be deleted. |
dellist |
|
an array of length num specifying the indices of the rows to be deleted. |
|
|
| Returns |
|
|
A zero value if the function terminated correctly, and a non-zero value if an error occurred.
|
|
| Description |
|
|
Use this function to delete a set of constraints from an existing LP problem, specifying the constraints as a list of indices. (Note that the constraints are numbered from 0 up to nrows-1, where nrows is the number of rows in the problem.)
|
|
| Example |
|
|
/* Assume p is an initialized LP problem with at least 4 rows. */
/* Use QSdelete_rows() to remove rows 1 and 3. */
int rval;
int dellist[2] = { 1, 3 };
rval = QSdelete_rows (p, 2, dellist);
if (rval) {
fprintf (stderr,
"QSdelete_rows failed with return code %d\n", rval);
}
