Detailed Description

Function Documentation

AlgError AlgConvolveD	(	int	sizeArrayCnv,
		double *	arrayCnv,
		int	sizeArrayKrn,
		double *	arrayKrn,
		int	sizeArrayDat,
		double *	arrayDat,
		AlgPadType	pad,
		double	padVal
	)

Convolves double 1D kernel and data arrays, cnv = krn * data. The return convolution array must not be aliased to either the kernel or data arrays.

Returns

Error code.

Parameters

sizeArrayCnv	Length of return array must be >= max(len(dat),len(krn)).
arrayCnv	Return convolution array.
sizeArrayKrn	Length of kernel array, must be odd.
arrayKrn	Kernel array.
sizeArrayDat	Length of data array.
arrayDat	Data array.
pad	Type of padding.
padVal	Padding value, only used when pad == ALG_PAD_VALUE.
