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

y = 1 y = 1×0 empty double row vector

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

y = 0.9564 0.7051 0.4416 0.0771 y = 0.7051 0.4416 0.0771 y = 0.7051 0.4416

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

y = 0.0177 0.2940 0.3873 0.8174 y = 0.2940 0.3873 0.8174 y = 0.2940 0.3873

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

y = 0.7116 0.8954 0.1942 0.8823 y = 0.8954 0.1942 0.8823 y = 0.8954 0.1942

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

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

y = 4×1 struct array with fields: a b y = 3×1 struct array with fields: a b y = 2×1 struct array with fields: a b
