T- the type of the field elements
public interface FieldFixedStepHandler<T extends RealFieldElement<T>>
This interface should be implemented by anyone who is interested
in getting the solution of an ordinary differential equation at
fixed time steps. Objects implementing this interface should be
wrapped within an instance of
FieldStepNormalizer that itself
is used as the general
FieldStepHandler by the integrator. The
FieldStepNormalizer object is called according to the integrator
internal algorithms and it calls objects implementing this
interface as necessary at fixed time steps.
|Modifier and Type||Method and Description|
Handle the last accepted step
Initialize step handler at the start of an ODE integration.
void init(FieldODEStateAndDerivative<T> initialState, T finalTime)
This method is called once at the start of the integration. It may be used by the step handler to initialize some internal data if needed.
initialState- initial time, state vector and derivative
finalTime- target time for the integration
void handleStep(FieldODEStateAndDerivative<T> state, boolean isLast)
state- current value of the independent time variable, state vector and derivative For efficiency purposes, the
FieldStepNormalizerclass reuses the same array on each call, so if the instance wants to keep it across all calls (for example to provide at the end of the integration a complete array of all steps), it should build a local copy store this copy.
isLast- true if the step is the last one
