ConjFlip

Computes the complex conjugate of a vector and stores the result in reverse order.

Syntax

IppStatus ippsConjFlip_16sc(const Ipp16sc* pSrc, Ipp16sc* pDst, int len);

IppStatus ippsConjFlip_32fc(const Ipp32fc* pSrc, Ipp32fc* pDst, int len);

IppStatus ippsConjFlip_64fc(const Ipp64fc* pSrc, Ipp64fc* pDst, int len);

Parameters

pSrc	Pointer to the source vector.
pDst	Pointer to the destination vector.
len	Number of elements in the vector.

Description

The function ippsConjFlip is declared in the ipps.h file. This function computes the conjugate of the vector pSrc and stores the result, in reverse order, in pDst. The complex conjugate, stored in reverse order, is defined as follows:

pDst[n] = conj(pSrc[len - n - 1]).

Note that if pSrc and pDst overlap in memory, the function returns unpredictable results.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pSrc or pDst pointer is NULL.
ippStsSizeErr	Indicates an error when len is less than or equal to 0.
