Parameters
- pSrc
- Pointer to the source vector.
- pMax
- 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 value of the input vector
pSrc
, and stores the result in
pMax
. If
pIndx
is not a
NULL
pointer, the function returns the index of the maximum element and stores it in
pIndx
. If there are several equal maximum elements, the first index from the beginning is returned.
Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error when one of the specified pointers isNULL.
- ippStsSizeErr
- Indicates an error whenlenis less than or equal to 0.
Example
The code example below demonstrates how to use the function
ippsMaxIndx
.Ipp16s src[] = { 1, -2, 3, 8, -6 }; Ipp16s max; int len = 5; int indx; ippsMaxIndx_16s ( src, len, &max, &indx );
Result:
max = 8 indx = 3
