Class HighamHall54Integrator

  • All Implemented Interfaces:
    FirstOrderIntegrator, ODEIntegrator

    public class HighamHall54Integrator
    extends EmbeddedRungeKuttaIntegrator
    This class implements the 5(4) Higham and Hall integrator for Ordinary Differential Equations.

    This integrator is an embedded Runge-Kutta integrator of order 5(4) used in local extrapolation mode (i.e. the solution is computed using the high order formula) with stepsize control (and automatic step initialization) and continuous output. This method uses 7 functions evaluations per step.

        Simple constructor. Build a fifth order Higham and Hall integrator with the given step bounds
        Parameters:
        minStep - minimal step (must be positive even for backward integration), the last step can be smaller than this
        maxStep - maximal step (must be positive even for backward integration)
        scalAbsoluteTolerance - allowed absolute error
        scalRelativeTolerance - allowed relative error
