Method Detail

initializeHighOrderDerivatives

Array2DRowRealMatrix initializeHighOrderDerivatives(double h,
                                                    double[] t,
                                                    double[][] y,
                                                    double[][] yDot)

Initialize the high order scaled derivatives at step start.

Parameters:

h - step size to use for scaling

t - first steps times

y - first steps states

yDot - first steps derivatives

Returns:

Nordieck vector at first step (h²/2 y''_n, h³/6 y'''_n ... h^k/k! y^(k)_n)
