INCREMENT back to summary

INCREMENT	back to summary
public static final StepNormalizerMode INCREMENT Steps are fixed increments of the start value. In other words, they are relative to the start value. If the integration start time is t0, then the points handled by the underlying fixed step size step handler are t0 (depending on the `bounds settings`), t0+h, t0+2h, ... If the integration range is an integer multiple of the step size (h), then the last point handled will be the end point of the integration (tend). If not, the last point may be the end point tend, or it may be a point belonging to the interval [tend - h ; tend], depending on the `bounds settings`. See Also `StepNormalizer`, `StepNormalizerBounds`

public static final StepNormalizerMode INCREMENT

Steps are fixed increments of the start value. In other words, they are relative to the start value.

If the integration start time is t0, then the points handled by the underlying fixed step size step handler are t0 (depending on the bounds settings), t0+h, t0+2h, ...

If the integration range is an integer multiple of the step size (h), then the last point handled will be the end point of the integration (tend). If not, the last point may be the end point tend, or it may be a point belonging to the interval [tend - h ; tend], depending on the bounds settings.

MULTIPLES back to summary

MULTIPLES	back to summary
public static final StepNormalizerMode MULTIPLES Steps are multiples of a fixed value. In other words, they are relative to the first multiple of the step size that is encountered after the start value. If the integration start time is t0, and the first multiple of the fixed step size that is encountered is t1, then the points handled by the underlying fixed step size step handler are t0 (depending on the `bounds settings`), t1, t1+h, t1+2h, ... If the end point of the integration range (tend) is an integer multiple of the step size (h) added to t1, then the last point handled will be the end point of the integration (tend). If not, the last point may be the end point tend, or it may be a point belonging to the interval [tend - h ; tend], depending on the `bounds settings`.
