Adds the elements of two vectors.

Syntax

Case 1. Not-in-place operations on floating point data, and integer data without scaling.

IppStatus ippsAdd_16s(const Ipp16s* pSrc1, const Ipp16s* pSrc2, Ipp16s* pDst, int len);

Case 2. Not-in-place operations on integer data with scaling.

Parameters

pSrc1, pSrc2	Pointers to the source vectors.
pDst	Pointer to the destination vector.
pSrc	Pointer to the source vector for in-place operations.
pSrcDst	Pointer to the source and destination vector for in-place operation.
len	Number of elements in the vector
scaleFactor	Scale factor, refer to Integer Scaling.

Description

This function adds the elements of the vector pSrc1 to the elements of the vector pSrc2, and stores the result in pDst.

The in-place flavors of ippsAdd add the elements of the vector pSrc to the elements of the vector pSrcDst and store the result in pSrcDst.

Functions with Sfs suffix perform scaling of the result value in accordance with the scaleFactor value. If the output value exceeds the data range, the result is saturated.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when any of the specified pointers is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
