Class ThreeEighthesIntegrator

java.lang.Object

org.spaceroots.mantissa.ode.RungeKuttaIntegrator

org.spaceroots.mantissa.ode.ThreeEighthesIntegrator

All Implemented Interfaces:

FirstOrderIntegrator

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
