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:

How to use it
To get a [PATRIUS (CommonsMath)] NumericalIntegrator object, we will just have to call for the getPatriusObject() method as below:
