Class TimeStampedFieldHermiteInterpolator<KK extends CalculusFieldElement<KK>>

java.lang.Object

org.orekit.time.AbstractFieldTimeInterpolator<TimeStampedField<KK>,KK>

org.orekit.time.TimeStampedFieldHermiteInterpolator<KK>

Type Parameters:

KK - type of the field elements

All Implemented Interfaces:

FieldTimeInterpolator<TimeStampedField<KK>,KK>

public class TimeStampedFieldHermiteInterpolator<KK extends CalculusFieldElement<KK>>
extends AbstractFieldTimeInterpolator<TimeStampedField<KK>,KK>

Hermite interpolator of time stamped field value.

As this implementation of interpolation is polynomial, it should be used only with small number of interpolation points (about 10-20 points) in order to avoid Runge's phenomenon and numerical problems (including NaN appearing).

Constructor Details

TimeStampedFieldHermiteInterpolator

public TimeStampedFieldHermiteInterpolator()

Constructor with :

• Default number of interpolation points of DEFAULT_INTERPOLATION_POINTS
• Default extrapolation threshold value (DEFAULT_EXTRAPOLATION_THRESHOLD_SEC s)

As this implementation of interpolation is polynomial, it should be used only with small number of interpolation points (about 10-20 points) in order to avoid Runge's phenomenon and numerical problems (including NaN appearing).

TimeStampedFieldHermiteInterpolator

public TimeStampedFieldHermiteInterpolator(int interpolationPoints)

Constructor with :

• Default extrapolation threshold value (DEFAULT_EXTRAPOLATION_THRESHOLD_SEC s)

As this implementation of interpolation is polynomial, it should be used only with small number of interpolation points (about 10-20 points) in order to avoid Runge's phenomenon and numerical problems (including NaN appearing).

Parameters:

interpolationPoints - number of interpolation points

TimeStampedFieldHermiteInterpolator

public TimeStampedFieldHermiteInterpolator(int interpolationPoints,
 double extrapolationThreshold)

Constructor.

As this implementation of interpolation is polynomial, it should be used only with small number of interpolation points (about 10-20 points) in order to avoid Runge's phenomenon and numerical problems (including NaN appearing).

Parameters:

interpolationPoints - number of interpolation points

extrapolationThreshold - extrapolation threshold beyond which the propagation will fail

Method Details

interpolate

protected TimeStampedField<KK> interpolate(AbstractFieldTimeInterpolator<TimeStampedField<KK>,KK>.InterpolationData interpolationData)

Interpolate instance from given interpolation data.

As this implementation of interpolation is polynomial, it should be used only with small samples (about 10-20 points) in order to avoid Runge's phenomenon and numerical problems (including NaN appearing).

Specified by:

interpolate in class AbstractFieldTimeInterpolator<TimeStampedField<KK extends CalculusFieldElement<KK>>,KK extends CalculusFieldElement<KK>>

Parameters:

interpolationData - interpolation data

Returns:

interpolated instance from given interpolation data.
