Mul

Multiplies accumulator and source vectors.

Syntax

IppStatus ipprMul_32f_C1IM(const Ipp32f* pSrc, const Ipp32s* pMask, Ipp32f* pSrcDst[3], int len);

IppStatus ipprMul_32f_C1P3IM(const Ipp32f* pSrc, const Ipp32s* pMask, Ipp32f* pSrcDst[3], int len);

Parameters

pSrc	Pointer to the source array.
pSrcDst	Pointer to the accumulator array for the 1-channel flavor, or pointer to the array of pointers to separate coordinate (x, y, z) planes of the accumulator array for planar flavor.
pMask	Pointer to the array of masks.
len	Number of rays.

Description

The function ipprMul is declared in the ippr.h file. This function multiplies each i-th element of the vectors of the accumulator pSrcDst by the corresponding element of the source vector pSrc in points where the mask pMask[i] is greater than or equal to 0. The result is stored in the pSrcDst.

The code example demonstrates how to use this function.

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.
