## mlib_VectorMerge_S16C_S16 (3MLIB)

### Name

mlib_VectorMerge_U8C_U8, mlib_VectorMerge_S8C_S8, mlib_VectorMerge_S16C_S16, mlib_VectorMerge_S32C_S32 - vertor merge

### Synopsis

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

mlib_status mlib_VectorMerge_U8C_U8(mlib_u8 *z, const mlib_u8 *r,
const mlib_u8 *i, mlib_s32 n);```
```mlib_status mlib_VectorMerge_S8C_S8(mlib_s8 *z, const mlib_s8 *r,
const mlib_s8 *i, mlib_s32 n);```
```mlib_status mlib_VectorMerge_S16C_S16(mlib_s16 *z, const mlib_s16 *r,
const mlib_s16 *i, mlib_s32 n);```
```mlib_status mlib_VectorMerge_S32C_S32(mlib_s32 *z, const mlib_s32 *r,
const mlib_s32 *i, mlib_s32 n);```

### Description

Each of these functions computes the complex vector from two vectors representing the real and imaginary parts.

The following equation is used:

```z[2*k]     = r[k]
z[2*k + 1] = i[k]
```

where k = 0, 1, ..., (n - 1).

### Parameters

Each of the functions takes the following arguments:

z

Pointer to the first complex element of the destination vector. z[2*k] contains the real part, and z[2*k + 1] contains the imaginary part.

r

Pointer to the first element of the real part.

i

Pointer to the first element of the imaginary part.

n

Number of elements in the vectors.

### Return Values

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