MaxAbsIndx

Returns the maximum absolute value of a vector and the index of the corresponding element.

Syntax

IppStatus ippsMaxAbsIndx_16s(const Ipp16s* pSrc, int len, Ipp16s* pMaxAbs, int* pIndx);

IppStatus ippsMaxAbsIndx_32s(const Ipp32s* pSrc, int len, Ipp32s* pMaxAbs, int* pIndx);

IppStatus ippsMaxAbsIndx_32f(const Ipp32f* pSrc, int len, Ipp32f* pMaxAbs, int* pIndx);IppStatus ippsMaxAbsIndx_64f(const Ipp64f* pSrc, int len, Ipp64f* pMaxAbs, int* pIndx);

Parameters

pSrc	Pointer to the source vector.
pMaxAbs	Pointer to the output result.
len	Number of elements in the vector.
pIndx	Pointer to the index value of the maximum element.

Description

This function returns the maximum absolute value pMaxAbs of the input vector pSrc, and the index of the corresponding element pIndx. If there are several elements with the equal maximum absolute value, the first index from the beginning is returned.

Return Values

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