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
sizeArrayCnvLength of return array must be >= max(len(dat),len(krn)).
arrayCnvReturn convolution array.
sizeArrayKrnLength of kernel array, must be odd.
arrayKrnKernel array.
sizeArrayDatLength of data array.
arrayDatData array.
padType of padding.
padValPadding value, only used when pad == ALG_PAD_VALUE.
