AdaptiveSStopper

public AdaptiveSStopper(double[] u0,

 double accuracy,
 SwimTrajectory trajectory)

Pathlength stopper

Parameters:

sf - final path length meters

accuracy - the accuracy

trajectory - optional trajectory

Method Details

stopIntegration

public boolean stopIntegration(double snew,
 double[] unew)

Description copied from interface: IAdaptiveStopper

Given the current state of the integration, should we stop? This allows the integration to stop, for example, if some distance from the origin has been exceeded or if the independent variable passes some threshold. It won't be precise, because the check may not happen on every step, but it should be close.

Returns:

true if we should stop now.
