public class OSnLNodeQTerm
extends OSnLNode

The OSnLNodeQTerm class represents an quadratic term node a quadratic expression. A quadratic term is of the form Cij*Xi*Xj, where Xi and Xj are the variables (i can be the same as j) and Cij is the corresponding coefficient. It extends the abstract OSnLNode class and implements its abstract methods such as calculateFunction(double[]).
