### Name

mlib_MatrixMaximum_U8, mlib_MatrixMaximum_S8, mlib_MatrixMaximum_S16, mlib_MatrixMaximum_S32, mlib_MatrixMaximum_F32, mlib_MatrixMaximum_D64 - find the maximum value in a matrix

### Synopsis

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

mlib_status mlib_MatrixMaximum_U8(mlib_u8 *max, const mlib_u8 *x,
mlib_s32 m, mlib_s32 n);```
```mlib_status mlib_MatrixMaximum_S8(mlib_s8 *max, const mlib_s8 *x,
mlib_s32 m, mlib_s32 n);```
```mlib_status mlib_MatrixMaximum_S16(mlib_s16 *max, const mlib_s16 *x,
mlib_s32 m, mlib_s32 n);```
```mlib_status mlib_MatrixMaximum_S32(mlib_s32 *max, const mlib_s32 *x,
mlib_s32 m, mlib_s32 n);```
```mlib_status mlib_MatrixMaximum_F32(mlib_f32 *max, const mlib_f32 *x,
mlib_s32 m, mlib_s32 n);```
```mlib_status mlib_MatrixMaximum_D64(mlib_d64 *max, const mlib_d64 *x,
mlib_s32 m, mlib_s32 n);```

### Description

Each of these functions finds the maximum value of all elements in a matrix.

It uses the following equation:

```max[0] = MAX{ x[i]  i = 0, 1, ..., (m*n - 1) }
```

### Parameters

Each of the functions takes the following arguments:

max

Pointer to the maximum value.

x

Pointer to the first element of the source matrix.

m

Number of rows in the source matrix.

n

Number of columns in the source matrix.

### Return Values

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