### Test Suite

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

x = 1×0 empty double row vector

Matrix index is out of range for deletion. Error in middleAsColumn (line 3) x(1)=[] Error in Test1 (line 3) assert(isequal(middleAsColumn(x),y_correct))

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

x = 0.8853 0.6092 0.8973 x = 0.6092 0.8973 ans = 0.6092 0.8973

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

x = 0.8547 0.1488 0.2288 x = 0.1488 0.2288 ans = 0.1488 0.2288

Assertion failed.

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

x = 0.9738 0.5434 0.0768 x = 0.5434 0.0768 ans = 0.5434 0.0768

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

x = 1×3 cell array {[1]} {[2]} {[3]} x = 1×2 cell array {[2]} {[3]} ans = 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 = 1×3 struct array with fields: a b x = 1×2 struct array with fields: a b ans = 2×1 struct array with fields: a b
