Function Documentation

◆ XLALCreateLanczosTriggerInterpolant()

LanczosTriggerInterpolant* XLALCreateLanczosTriggerInterpolant ( unsigned int window )

Constructor.

Allocate a new interpolation workspace and return a pointer to it, or NULL if an error occurs.

Definition at line 453 of file TriggerInterpolation.c.

◆ XLALDestroyLanczosTriggerInterpolant()

void XLALDestroyLanczosTriggerInterpolant ( LanczosTriggerInterpolant * interp )

Destructor.

If the workspace is non-NULL, deallocate it.

Definition at line 473 of file TriggerInterpolation.c.

◆ XLALCOMPLEX16ApplyLanczosTriggerInterpolant()

int XLALCOMPLEX16ApplyLanczosTriggerInterpolant	(	LanczosTriggerInterpolant *	interp,
		double *	tmax,
		COMPLEX16 *	ymax,
		const COMPLEX16 *	y
	)

Perform interpolation using the allocated workspace.

Perform interpolation around the matched-filter output data pointed to by y. There should exist window samples before and window samples after this pointer.

On success, set *tmax to the interpolated time, *ymax to the complex interpolated signal, and return 0. On failure, return a non-zero GSL error code.
