Purpose

Topic area
Synopsis
int XPRS_CC XPRSgetrowflags(XPRSprob prob, int flags[], int first, int last);
Arguments
prob 
The current problem
flags 
Int array of length last-first+1 where type of information (see below) will be returned
first 
First row index to be checked
last 
Last row index to be checked
Example
The following example will print all three messages if the row at index 1 of the problem is an indicator constraint involving a quadratic matrix:
int flags[2];
...
XPRSgetrowflags(prob,1,2,flags);
if (flags[0] & (XPRS_ROWFLAG_QUADRATIC)) { printf("the second row is quadratic" }
if (flags[0] & (XPRS_ROWFLAG_INDICATOR)) { printf("the second row is an indicator" }
if (flags[0] & (XPRS_ROWFLAG_QUADRATIC+XPRS_ROWFLAG_INDICATOR)) { printf("the second row is a quadratic indicator" }
Further information
The flags array returns a bitvector for each row defining all the information that is currently attached to that row:
XPRS_ROWFLAG_QUADRATIC
The row has quadratic coefficients.
XPRS_ROWFLAG_DELAYED
The row is marked as a delayed row.
XPRS_ROWFLAG_MODELCUT
The row is marked as a model cut.
XPRS_ROWFLAG_INDICATOR
The row is used as an indicator.
XPRS_ROWFLAG_NONLINEAR
The row has nonlinear coefficients.
