| Purpose |
|
|
Delete a single column from the problem.
|
|
| Synopsis |
|
|
int QSdelete_col (QSprob p, int colindex)
|
|
| Arguments |
|
p |
|
a handle to an initialized problem. |
colindex |
|
the index of the column 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 single variable from an existing LP problem; the interface is slightly easier than that of QSdelete_cols. (Note that the variables are numbered from 0 up to ncols-1, where ncols is the number of columns in the problem.)
|
|
| Example |
|
|
/* Assume p is an initialized LP problem with at least 5 columns. */
/* Use QSdelete_col() to remove column 4. */
int rval;
rval = QSdelete_col (p, 4);
if (rval) {
fprintf (stderr, "QSdelete_col failed with return code %d\n", rval);
}
