XSLPchgrowstatus

Purpose

Change the status setting of a constraint

Synopsis

int XPRS_CC XSLPchgrowstatus(XSLPprob Prob, int RowIndex, int *Status);

Arguments

Prob

The current SLP problem.

RowIndex

The index of the matrix row to be changed.

Status

Address of an integer holding a bitmap with the new status settings. If the status is to be changed, always get the current status first (use XSLPgetrowstatus) and then change settings as required. The only settings likely to be changed are:

Bit 11

Set if row must not have a penalty error vector. This is the equivalent of an enforced constraint (SLPDATA type EC).

Example

The following example changes the status of row 9 to be an enforced constraint.

int RowIndex, Status;
RowIndex = 9;
XSLPgetrowstatus(Prob,RowIndex,&Status);
Status = Status | (1<<11);
XSLPchgrowstatus(Prob,RowIndex,&Status);

Further information

If Status is NULL the current status will remain unchanged.
