| Purpose |
|
|
Get the current basis.

|
| Synopsis |
|
|
QSbas QSget_basis (QSprob p)
|
|
| Arguments |
|
p |
|
a handle to an initialized problem. |
|
|
| Returns |
|
|
An initialized QSbas object, providing a handle to the current basis for the LP problem. If an error occurred, the QSbas object is set to NULL. Note that QSget_basis returns an error code if it is called with a specified problem that has not been solved with one of the optimization functions ( QSopt_dual or QSopt_primal) since the last time the problem was loaded or modified.
|
|
| Description |
|
|
This function can be used to obtain a copy of the current basis; the basis can later be used with a call to QSload_basis when re-solving the LP problem. When a application no longer requires the QSbas data structure, the function QSfree_basis should be call to free the associated memory.
|
|
| Example |
|
|
/* p is an initialized QSprob, a handle to an existing LP problem */
QSbas B;
B = QSget_basis (p);
if (B == (QSbas) NULL) {
fprintf (stderr, "Could not obtain the basis\n");
}
