Constructor	Description
TimeStampedDoubleAndDerivativeHermiteInterpolator()	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).
TimeStampedDoubleAndDerivativeHermiteInterpolator(int interpolationPoints)	Constructor with default extrapolation threshold value (DEFAULT_EXTRAPOLATION_THRESHOLD_SEC s).

Constructor Details

TimeStampedDoubleAndDerivativeHermiteInterpolator

public TimeStampedDoubleAndDerivativeHermiteInterpolator()

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).

TimeStampedDoubleAndDerivativeHermiteInterpolator

public TimeStampedDoubleAndDerivativeHermiteInterpolator(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

TimeStampedDoubleAndDerivativeHermiteInterpolator

public TimeStampedDoubleAndDerivativeHermiteInterpolator(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
