Purpose
Delete a quadratic term from a constraint.
Synopsis
int XPRBdelqterm(XPRBctr ctr, XPRBvar var1, XPRBvar var2);
Arguments
ctr 
Reference to a constraint.
var1 
Reference to a variable.
var2 
Reference to a variable (not necessarily different).
Return value
0 if function executed successfully, 1 otherwise.
Example
The following example first adds the term 5.2*x2*x2 to the constraint ctr1 and then deletes this term from the constraint: 
XPRBctr ctr1;
XPRBvar x2,x4;
 ...
ctr1 = XPRBnewctr(prob, "r1", XPRB_L);
x2 = XPRBnewvar(prob, XPRB_PL, "abc1", 0, XPRB_INFINITY);
XPRBaddqterm(ctr1, x2, x2, 5.2);
XPRBdelqterm(ctr1, x2, x2);
Further information
This function deletes a quadratic term from a constraint, comprising the product of the variables var1 and var2.
