pub struct QuadExpr {
// some fields omitted
}Quadratic expression of variables
A quadratic expression consists of a linear expression and a set of variable-variable-coefficient triples to express the quadratic term.
Methods
impl QuadExpr[src]
fn new() -> Self
fn add_term(self, coeff: f64, var: Var) -> Self
Add a linear term into the expression.
fn add_qterm(self, coeff: f64, row: Var, col: Var) -> Self
Add a quadratic term into the expression.
fn add_constant(self, constant: f64) -> Self
Add a constant into the expression.
fn get_value(&self, model: &Model) -> Result<f64>
Get actual value of the expression.
