Detailed Description

A quadratic coefficient.

A quadratic coefficient is a (variable,variable)/value pair that gives the factor for a pair of variables in a quadratic expression.

Constructor & Destructor Documentation

QuadCoef() [1/4]

xpress::objects::QuadCoef::QuadCoef ( QPair variables,
double coefficient )
inline

Create a coefficient.

Parameters
variables The variables in the coefficient.
coefficient Value multiplying the variables in the coefficient.
Since
44.00

QuadCoef() [2/4]

xpress::objects::QuadCoef::QuadCoef ( Variable var1,
Variable var2,
double coefficient )
inline

Create a coefficient.

Note that the constructor puts var1 and var2 into a canonical ordering and may thus change their order.

Parameters
var1 First variable in coefficient.
var2 Second variable in coefficient.
coefficient Value multiplying the variables in coefficient.
Since
44.00

QuadCoef() [3/4]

xpress::objects::QuadCoef::QuadCoef ( QuadCoef const & other )
inline
Since
44.00

QuadCoef() [4/4]

xpress::objects::QuadCoef::QuadCoef ( )
inline

Create a coefficient with default values.
