XPRBgetqcoeff

XPRBgetqcoeff

Purpose
Get the coefficient of a quadratic constraint term.
Synopsis
double XPRBgetqcoeff(XPRBctr ctr, XPRBvar var1, XPRBvar var2);
Arguments
ctr 
BCL reference to a previously created constraint.
var1 
BCL reference to a variable.
var2 
BCL reference to a variable (not necessarily different from first variable).
Return value
Coefficient of the variable in the specified constraint or 0 if the variable does not occur.
Example 
XPRBprob expl2;
XPRBctr ctr1;
XPRBvar x1;
double val;
   ...
expl2 = XPRBnewprob("example2");
x1 = XPRBnewvar(expl2, XPRB_UI, "abc3", 0, 100);
ctr1 = XPRBnewctr(expl2, "r1", XPRB_E);
XPRBaddqterm(ctr1, x1, x1, 5.4);
val = XPRBgetqcoeff(ctr1, x1, x1);
This retrieves the coefficient of the quadratic term x1*x1 in the constraint ctr1.
Further information
This function returns the coefficient of a given quadratic term var1*var2 in the constraint ctr. Return value 0 indicates that the term is not contained in the constraint.
