Parameters

pSrc	Pointer to the source vector.
pMin	Pointer to the minimum value.
pMax	Pointer to the maximum value.
len	Number of elements in the vector.
pMinIndx	Pointer to the index value of the minimum element.
pMaxIndx	Pointer to the index value of the maximum element.

Description

The function ippsMinMaxIndx is declared in the ipps.h file. This function returns the minimum and maximum values of the input vector pSrc and stores the result in pMin and pMax, respectively. The function also returns the indexes of the minimum and maximum elements and stores them in pMinIndx and pMaxIndx, respectively. If there are several equal minimum or maximum elements, the first index from the beginning is returned.

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.
