DotProdCol

Calculates the dot product of taps vector and columns of the specified set of rows.

Syntax

IppStatus ippiDotProdCol_32f_L2(const Ipp32f* const ppSrcRow[], const Ipp32f* pTaps, int tapsLen, Ipp32f* pDst, int width);

IppStatus ippiDotProdCol_64f_L2(const Ipp64f* const ppSrcRow[], const Ipp64f* pTaps, int tapsLen, Ipp64f* pDst, int width);

Parameters

ppSrcRow	Pointer to the set of rows.
pTaps	Pointer to the taps vector.
tapsLen	Length of taps vector, is equal to the number of rows.
pDst	Pointer to the destination row.
width	Width of the source and destination rows.

Description

The function ippiDotProdCol is declared in the ippi.h file.

This function calculates the dot product of taps vector pTaps and columns of the specified set of the rows ppSrcRow. It is useful for external vertical filtering pipeline implementation.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error.
ippStsNullPtrErr	Indicates an error condition if one of the specified pointers is NULL.
ippStsSizeErr	Indicates an error condition if width is less than or equal to 0.
