| Purpose |
|
|
Delete a column specified by name.
|
|
| Synopsis |
|
|
int QSdelete_named_column (QSprob p, const char *colname)
|
|
| Arguments |
|
p |
|
a handle to an initialized problem. |
colname |
|
a string specifying the name of a column (variable) to be deleted. |
|
|
| Returns |
|
|
A zero value if the function terminated correctly, and a non-zero value if an error occurred. If the column is not in the LP problem, an error will be returned.
|
|
| Description |
|
|
Use this function to delete a single variable from an existing LP problem by specifying the name of the variable; the interface is slightly easier than that of QSdelete_named_columns_list.
|
|
| Example |
|
|
/* Assume p is an initialized LP problem. */
/* Delete variable z. */
int rval;
rval = QSdelete_named_column (p, "z");
if (rval) {
fprintf (stderr,
"could not delete variable, error code %d\n", rval);
}
