Class ClassicalRungeKuttaIntegrator

java.lang.Object
  org.spaceroots.mantissa.ode.RungeKuttaIntegrator
      org.spaceroots.mantissa.ode.ClassicalRungeKuttaIntegrator

All Implemented Interfaces:

FirstOrderIntegrator

public class ClassicalRungeKuttaIntegrator

extends RungeKuttaIntegrator

This class implements the classical fourth order Runge-Kutta integrator for Ordinary Differential Equations (it is the most often used Runge-Kutta method).

This method is an explicit Runge-Kutta method, its Butcher-array is the following one :

    0  |  0    0    0    0
   1/2 | 1/2   0    0    0
   1/2 |  0   1/2   0    0
    1  |  0    0    1    0
       |--------------------
       | 1/6  1/3  1/3  1/6
