XSLPchgrowstatus

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.
