All Implemented Interfaces:

Integrator<Double,Double,Function<Double,Double>>
```
public class AdaptiveCompositeIntegrator1D
extends Integrator1D<Double,Double>
```
Adaptive composite integrator: step size is set to be small if functional variation of integrand is large The integrator in individual intervals (base integrator) should be specified by constructor.
