Purpose
Get the
row number for a constraint.
Synopsis
int XPRBgetrownum(XPRBctr ctr);
Argument
|
ctr
|
Reference to a previously created constraint.
|
Return value
Row number (non-negative value), or a negative value.
Example
The following gets the row number of ctr1.
XPRBprob prob;
XPRBctr ctr1;
...
int rindex;
ctr1 = XPRBnewctr(prob, "r1", XPRB_E);
rindex = XPRBgetrownum(ctr1);
Further information
This function returns the matrix row number of a constraint. If the matrix has not yet been generated or the constraint is
not part of the matrix (constraint type
XPRB_N or no non-zero terms) then the return value is negative. To check whether the matrix has been generated, use function
XPRBgetprobstat. The counting of row numbers starts with
0.
