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

x = 1 y = 1×0 empty double row vector

Assertion failed.

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

x = 0.3909 0.6142 0.3549 0.4745 y = 0.6142 0.3549

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

x = 0.2558 0.3357 0.2641 0.6991 y = 0.3357 0.2641

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

x = 0.1729 0.5133 0.4360 0.2424 y = 0.5133 0.4360

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

x = 4×1 cell array {[1]} {[2]} {[3]} {[4]} y = 2×1 cell array {[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))

x = 4×1 struct array with fields: a b y = 2×1 struct array with fields: a b
