### Test Suite

Test Status Code Input and Output
1   Pass
%% x = 1; y_correct = zeros(0,1); assert(isequal(middleAsColumn(x),y_correct))

``` a = Empty matrix: 1-by-0 ans = Empty matrix: 0-by-1 ```

2   Pass
%% x = rand(1,4); y_correct = x(2:3)'; assert(isequal(middleAsColumn(x),y_correct))

``` a = 0.1285 0.4574 ans = 0.1285 0.4574 ```

3   Fail
%% x = rand(4,1); y_correct = x(2:3); assert(isequal(middleAsColumn(x),y_correct))

```Error: Output argument "ans" (and maybe others) not assigned during call to "/users/msssystem9/middleAsColumn.m>middleAsColumn". ```

4   Pass
%% x = rand(2,2); y_correct = x(2:3)'; assert(isequal(middleAsColumn(x),y_correct))

``` a = 0.9950 0.9898 ans = 0.9950 0.9898 ```

5   Pass
%% x = {1 2 3 4}; y_correct = x(2:3)'; assert(isequal(middleAsColumn(x),y_correct))

``` a = [2] [3] ans = [2] [3] ```

6   Pass
%% x = struct('a',{1 2 3 4},'b',{3 4 5 6}); y_correct = x(2:3)'; assert(isequal(middleAsColumn(x),y_correct))

``` a = 1x2 struct array with fields: a b ans = 2x1 struct array with fields: a b ```
