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
