Computes the dot product of two vectors.
Syntax
IppStatus ippsDotProd_G729A_16s32s (const Ipp16s* pSrc1, const Ipp16s* pSrc2, int len, Ipp32s* pDp);
IppStatus ippsDotProd_G729A_32f(const Ipp32f* pSrc1, const Ipp32f* pSrc2, int len, Ipp32f* pDp);
Parameters
pSrc1 |
Pointer to the first source vector. |
pSrc2 |
Pointer to the second source vector. |
len |
Number of elements in each vector. |
pDp |
Pointer to the output result. |
Description
The functions ippsDotProd_G729A are declared in the ippsc.h file. The function ippsDotProd_G729A_16s32s computes the dot product of two source vectors pSrc1 and pSrc2 as:
while for the ippsDotProd_G729A_32f function the result is
Vectors pSrc1 and pSrc2 must have the same length, len.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when the pSrc1, pSrc2, or pDp pointer is NULL. |
ippStsSizeErr |
Indicates an error when len is less than or equal to 0. |
ippStsOverflow |
Indicates a warning that at least one result value was saturated. |
