XPRBaddcutarrterm

Purpose
Add multiple linear terms to a cut.
Synopsis
int XPRBaddcutarrterm(XPRBcut cut, XPRBarrvar av, double *coeff);
Arguments
cut 
Reference to a cut.
av 
Reference to an array of variables.
coeff 
Values to be added to the coefficients of the variables in the array (the number of coefficients must correspond to the size of the array of variables).
Return value
0 if function executed successfully, 1 otherwise.
Example
Add the term ∑
4
i=0
cri· ty1i to the cut cut1. 
XPRBcut cut1;
XPRBarrvar ty1;
double cr[] = {2.0, 13.0, 15.0, 6.0, 8.5};
XPRBprob expl1;
expl1 = XPRBnewprob("cutexample");
ty1 = XPRBnewarrvar(expl1, 5, XPRB_PL, "arry1", 0, 500);
cut1 = XPRBnewcut(expl1, XPRB_E, 1);
XPRBaddcutarrterm(cut1, ty1, cr);
Further information
This function adds multiple linear terms to a cut, the variables coming from array av and the corresponding coefficients from coeff. If the cut already has a term with one of the variables, the corresponding value from coeff is added to its coefficient.
Note:
all terms that are added to a cut must belong to the same problem as the cut itself.
