Hi,

Say you have a function dy/dt = f(y). Then, you would
do the following in code:

// create inner class representing function
Mapping func = new Mapping() {
public double map(double y) {
return f(y);
}
};
int N = 50;
double dt = 0.1;
double[] yValues = new double[N]; // will contain y_i
yValues[0] = y0; // set initial condition
NumericalMath.rungeKutta(yValues, func, dt);
// can now plot yValues to see result

I'll improve the docs for this.

Regards,

Mark
