### Synopsis

```cc [ flag... ] file... –lmlib [ library... ]
#include <mlib.h>

mlib_status mlib_VectorMaximumMag_U8C(mlib_u8 *max,
const mlib_u8 *x, mlib_s32 n);```
```mlib_status mlib_VectorMaximumMag_S8C(mlib_s8 *max,
const mlib_s8 *x, mlib_s32 n);```
```mlib_status mlib_VectorMaximumMag_S16C(mlib_s16 *max,
const mlib_s16 *x, mlib_s32 n);```
```mlib_status mlib_VectorMaximumMag_S32C(mlib_s32 *max,
const mlib_s32 *x, mlib_s32 n);```
```mlib_status mlib_VectorMaximumMag_F32C(mlib_f32 *max,
const mlib_f32 *x, mlib_s32 n);```
```mlib_status mlib_VectorMaximumMag_D64C(mlib_d64 *max,
const mlib_d64 *x, mlib_s32 n);```

### Description

Each of these functions finds the first element with the maximum magnitude in a complex vector, then puts the real and imaginary parts of it into max[0] and max[1], respectively.

### Parameters

Each of the functions takes the following arguments:

max

Pointer to the first element with the maximum magnitude.

x

Pointer to the first element of the source vector.

n

Number of elements in the source vector.

### Return Values

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
