| Purpose |
|
|
Delete a list of rows, specified by names.
|
|
| Synopsis |
|
|
int QSdelete_named_rows_list (QSprob p, int num, const char **rownames)
|
|
| Arguments |
|
p |
|
a handle to an initialized problem. |
num |
|
the number of rows to be deleted. |
rownames |
|
an array of length num; the entries in the array are strings specifying the names of the rows (constraints) to be deleted. |
|
|
| Returns |
|
|
A zero value if the function terminated correctly, and a non-zero value if an error occurred. If one or more of the rows is not in the LP problem, an error will be returned.
|
|
| Description |
|
|
This function can be used to delete a set constraints from an existing LP problem by specifying the names of the constraints in a list. It is more efficient to use this function then to use repeated calls to QSdelete_named_row.
|
|
| Example |
|
|
/* Assume p is an initialized LP problem. */
/* Delete constraints r0 and r2. */
int rval;
const char *dlist[2] = { "r0", "r2" };
rval = QSdelete_named_rows_list (p, 2, dlist);
if (rval) {
fprintf (stderr, "could not delete rows, error code %d\n", rval);
}
