AddMulMul

Multiplies two source vectors and adds product to the accumulator.

Syntax

IppStatus ipprAddMulMul_32f_AC1P3IM(IppPoint3D_32f point, const Ipp32f* pSrc0, const Ipp32f* const pSrc1[3], const Ipp32s* pMask, Ipp32f* pSrcDst[3], int len);

Parameters

point	Source point.
pSrc0	Pointer to the first source array.
pSrc1	Pointer to the array of pointers to separate coordinate (x, y, z) planes of the second source points.
pSrcDst	Pointer to the array of pointers to separate coordinate (x, y, z) planes of the accumulator array.
pMask	Pointer to the array of masks.
len	Number of of rays.

Description

The function ipprAddMulMul is declared in the ippr.h file. This function multiplies the elements of source vectors pSrc0 and pSrc1, and stores results in the accumulator pSrcDst in accordance with the following formulas:

pSrcDst [0][n] += pSrc1[0][ n] * pSrc0[n] * point[0],

pSrcDst [1][n] += pSrc1[1][ n] * pSrc0[n] * point[1],

pSrcDst [2][n] += pSrc1[2][ n] * pSrc0[n] * point[2],

where n = 0, 1, 2,.. len -1.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error condition if one of the specified pointers is `NULL`.
