DiscreteFunction (tensorics-core API)

Type Parameters:

X - the type of the values in x-direction (Independent variable)

Y - the type of the values in y-direction (Dependent variable)

All Superinterfaces:

java.util.function.Function<X,Y>, MathFunction<X,Y>

All Known Subinterfaces:

InterpolatedFunction<X,Y>

All Known Implementing Classes:

```
public interface DiscreteFunction<X,Y>
extends MathFunction<X,Y>
```
A function which has only a discrete set of points (X/Y pairs). The apply(Object) method will throw an IllegalDiscreteFunctionUsageException if a Y value is requested for an unknown X.
