The given MATLAB commands are:

```matlab
A = [ 1 2 ];
B = [ 3 4 ];
C = [ A' [ B; B] ]';
```

Let's break it down:

1. `A = [ 1 2 ];` This command creates a row vector A with elements 1 and 2.

2. `B = [ 3 4 ];` This command creates a row vector B with elements 3 and 4.

3. `[ B; B]` This command concatenates vector B with itself vertically, resulting in a 2x2 matrix:

```matlab
[ 3 4
3 4 ]
```

4. `A'` This command transposes vector A, changing it from a row vector to a column vector:

```matlab
[ 1
2 ]
```

5. `[ A' [ B; B] ]'` This command concatenates the transposed A and the 2x2 matrix vertically, and then transposes the result. The final matrix C is:

```matlab
[ 1 3 3
2 4 4 ]
```

So, the value of C after the given MATLAB command is a 2x3 matrix:

```matlab
[ 1 3 3
2 4 4 ]
```

Question

The given MATLAB commands are:
