public class ThreeEighthesIntegrator extends RungeKuttaIntegrator
This class implements the 3/8 fourth order Runge-Kutta integrator for Ordinary Differential Equations.This method is an explicit Runge-Kutta method, its Butcher-array is the following one :
0 | 0 0 0 0 1/3 | 1/3 0 0 0 2/3 |-1/3 1 0 0 1 | 1 -1 1 0 |-------------------- | 1/8 3/8 3/8 1/8- Since:
