   +----ChaosDemos.ode
public class ode
extends Object
Class to advance ODE's through single time step.
Uses 5th order Runga-Kutta method with given timestep and embedded 4th order method for error checking. (See Numerical Recipes, 16.2)

Parameters:
target - calling class
n - number of OSDs

Methods

o timeStep 
 public double timeStep(double x[],
                        double t,
