    - #### 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 ... hk/k! y(k)n)
