How to call it

For using the GPIntegrator class, the developer has only to create such an object with these two possibilities:

  • With no initialization:
GPIntegrator gpInteg = new GPIntegrator();

In that case, all the possible integrators will be displayed (i.e. Runge Kutta 4, Runge Kutta 6 and Dormand Price 853)

  • Or, if we want to limit the display to some of these integrators (in the example below, only Runge Kutta 4 and Dormand Price 853) and choose the one initially displayes (here the Dormand Price 853 one):
final IntegratorTypeEnum[] types = { IntegratorTypeEnum.RK4, IntegratorTypeEnum.DOP };
GPIntegrator gpInteg = new GPIntegrator(types, IntegratorTypeEnum.DOP);
  • There are also several setter methods to override default values. For example, if we want to display by default 5 seconds for the Runge Kutta time steps, we will have to call to the specific method as:
gpInteg.setRKParameters(5.);

Display

For the first cases, the display will be:
