Method Summary

Modifier and Type	Method and Description
default T	interpolate(FieldAbsoluteDate<KK> date, Collection<T> sample) Get an interpolated instance.
T	interpolate(FieldAbsoluteDate<KK> date, Stream<T> sample) Get an interpolated instance.

Method Detail

interpolate

default T interpolate(FieldAbsoluteDate<KK> date,
                      Collection<T> sample)
               throws OrekitException

Get an interpolated instance.

Note that the state of the current instance may not be used in the interpolation process, only its type and non interpolable fields are used (for example central attraction coefficient or frame when interpolating orbits). The interpolable fields taken into account are taken only from the states of the sample points. So if the state of the instance must be used, the instance should be included in the sample points.

Note that this method is designed for small samples only (say up to about 10-20 points) so it can be implemented using polynomial interpolation (typically Hermite interpolation). Using too much points may induce Runge's phenomenon and numerical problems (including NaN appearing).

Parameters:

date - interpolation date

sample - sample points on which interpolation should be done

Returns:

a new instance, interpolated at specified date

Throws:

OrekitException - if interpolation cannot be performed

interpolate

T interpolate(FieldAbsoluteDate<KK> date,
              Stream<T> sample)
       throws OrekitException

Parameters:

date - interpolation date

sample - sample points on which interpolation should be done

Returns:

a new instance, interpolated at specified date

Throws:
