double QGpCoreWave::AutocorrDispersion::derivative

(

double

k

)

QVector< double > QGpCoreWave::AutocorrDispersion::dispersion	(	const FactoryPoint &	autocorr,
		double	kmin,
		double	kmax
	)

Returns all the dispersion curve solutions for autocorr between kmin and kmax. The returned values are slowness sorted in ascending order.
