Class RungeKuttaNs


public class RungeKuttaNs extends Object
Provides an implementation of the Runge-Kutta method for solving single or sets of ordinary differential equations (ODEs).

A set of ODEs are supplied by means of the interface DiffnFunction.

This class is taken from the Java library developed by Michael Thomas Flanagan available at

      public static double[] fourthOrder(DiffnFunctionNs g, long tOld, double[] y0, long tNew, long tStepMax, long tUnit)
      Returns the value of y at a given value of x (xn) for a set of ordinary differential equation (ODEs)
      g - an implementation of DiffnFunction describing a set of Ordinary Differential Equations
      tOld - the initial value for t
      y0 - the initial value for y
      tNew - the value of t where we want to know y
      tStepMax - the initial step size
      tUnit - the time unit used for the derivatives
      the value of y at xn
