XPRBaddterm

Purpose

Add a term to a constraint.

Synopsis

int XPRBaddterm(XPRBctr ctr, XPRBvar var, double coeff);

Arguments

ctr

BCL reference to a constraint, resulting from XPRBnewctr.

var

BCL reference to a variable. May be NULL if not required.

coeff

Amount to be added to the coefficient of the variable var.

Return value

0 if function executed successfully, 1 otherwise.

Example
XPRBprob prob;
XPRBctr ctr1;
XPRBvar x1;
   ...
x1 = XPRBnewvar(prob, XPRB_UI, "abc3", 0, 100);
ctr1 = XPRBnewctr(prob, "r1", XPRB_E);
XPRBaddterm(ctr1, x1, 5.4);
This adds the term 5.4*x1 to the constraint ctr1.

Further information

This function adds a new term to a constraint, comprising the variable var with coefficient coeff. If the constraint already has a term with variable var, coeff is added to its coefficient. If var is set to NULL, the value coeff is added to the right hand side of the constraint.
