IirConvolveCanonicProgressive()

int IirConvolveCanonicProgressive	(	double	InputData[],
		double	OutputData[],
		long	SignalLength,
		double	Kernel[],
		double	RightInit[],
		long	KernelLength
	)

Canonic progressive. Computes OutputData[i] = InputData[i] + SUM(k): OutputData[i + k + 1] * Kernel[k]. The input and the output have the same length. The kernel and the initial output values have the same length.

success: return(!ERROR); failure: return(ERROR)

IirConvolveCanonicRegressive()

int IirConvolveCanonicRegressive	(	double	InputData[],
		double	OutputData[],
		long	SignalLength,
		double	Kernel[],
		double	LeftInit[],
		long	KernelLength
	)

Canonic regressive. Computes OutputData[i] = InputData[i] + SUM(k): OutputData[i - k - 1] Kernel[k]. The input and the output have the same length. The kernel and the initial output values have the same length.

success: return(!ERROR); failure: return(ERROR)

IirConvolvePoles()

int IirConvolvePoles	(	double	InputData[],
		double	OutputData[],
		long	SignalLength,
		double	RealPoles[],
		long	PoleNumber,
		enum TBoundaryConvention	Convention,
		double	Tolerance
	)

The filter is defined by its poles (1D). The input and the output have the same length. In-place processing is allowed. No more than two poles are allowed for a finite support boundary.

success: return(!ERROR); failure: return(ERROR)

IirConvolvePolesVolume()

int IirConvolvePolesVolume	(	double *	VolumeSource,
		double *	VolumeDestination,
		long	Nx,
		long	Ny,
		long	Nz,
		double	RealPoles[],
		long	PoleNumber,
		enum TBoundaryConvention	Convention,
		double	Tolerance,
		int *	Status
	)

The filter is defined by its poles (3D). No more than two poles are allowed for a finite support boundary. VolumeSource is a (double)volume of size (Nx x Ny x Nz). OutputData is a (double)volume of size (Nx x Ny x Nz).

success: return(!ERROR); failure: return(ERROR)
