Examples of StepNormalizer

org.apache.commons.math.ode.StepNormalizer
This class wraps an object implementing {@link FixedStepHandler}into a {@link StepHandler}.
This wrapper allows to use fixed step handlers with general integrators which cannot guaranty their integration steps will remain constant and therefore only accept general step handlers.

The stepsize used is selected at construction time. The {@link FixedStepHandler#handleStep handleStep} method of the underlying{@link FixedStepHandler} object is called at the beginning time ofthe integration t0 and also at times t0+h, t0+2h, ... If the integration range is an integer multiple of the stepsize, then the last point handled will be the endpoint of the integration tend, if not, the last point will belong to the interval [tend - h ; tend].

There is no constraint on the integrator, it can use any timestep it needs (time steps longer or shorter than the fixed time step and non-integer ratios are all allowed).
