MaxAbs

Returns the maximum absolute value of a vector.

Syntax

IppStatus ippsMaxAbs_16s(const Ipp16s* pSrc, int len, Ipp16s* pMaxAbs);

IppStatus ippsMaxAbs_32s(const Ipp32s* pSrc, int len, Ipp32s* pMaxAbs);

IppStatus ippsMaxAbs_32f(const Ipp32f* pSrc, int len, Ipp32f* pMaxAbs);

IppStatus ippsMaxAbs_64f(const Ipp64f* pSrc, int len, Ipp64f* pMaxAbs);

Include Files

Domain Dependencies

Headers: ippcore.h, ippvm.h

Libraries: ippcore.lib, ippvm.lib

Parameters

pSrc

Pointer to the source vector.

pMaxAbs

Pointer to the output result.

len

Number of elements in the vector.

Description

This function returns the maximum absolute value of the input vector pSrc, and stores the result in pMaxAbs.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when the pMaxAbs or pSrc pointer is NULL.

ippStsSizeErr

Indicates an error when len is less than or equal to 0.

Example

The example below shows how to use the function ippsMaxAbs_16s.

Ipp16s src[5] = { 2, -8, -3, -1, 7 }; 
Ipp16s maxAbs;
ippsMaxAbs_16s ( src, 5, &maxAbs );

Result:

maxAbs = 8
