Calculates autocorrelation of a vector.
Syntax
IppStatus ippsAutoCorr_16s32s (const Ipp16s* pSrc, int srcLen, Ipp32s* pDst, int dstLen);
Parameters
pSrc |
Pointer to the first source vector [srcLen]. |
srcLen |
Length of the source vector. |
pDst |
Pointer to the destination vector [dstLen]. |
dstLen |
Length of the destination vector (the number of autocorrelation values to calculate). |
Description
The function ippsAutoCorr is declared in the ippsc.h file. This function calculates autocorrelation of the input vector as follows:
Here n = 0,...,dstLen -1 .
and stores the result in pDst.
Return Values
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when the pSrc or pDst pointer is NULL. |
ippStsSizeErr |
Indicates an error when srcLenor dstLen is less or equal to 0. |
