java.lang.Object

org.spaceroots.mantissa.ode.RungeKuttaIntegrator

org.spaceroots.mantissa.ode.MidpointIntegrator

All Implemented Interfaces:

FirstOrderIntegrator

public class MidpointIntegrator
extends RungeKuttaIntegrator

This class implements a second 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
   1/2 | 1/2   0
       |----------
       |  0    1
