Test Suite

Test Status Code Input and Output
1   Fail
x = [1 2 3 4]; y_correct = [2 3 4]; assert(isequal(last_three(x),y_correct))

Assertion failed.

2   Fail
x = [5;2;8;6;7;2;3]; y_correct = [7;2;3]; assert(isequal(last_three(x),y_correct))

Index in position 2 exceeds array bounds (must not exceed 1). Error in last_three (line 6) y = x(size(x,1)-3,size(x,1)); Error in Test2 (line 3) assert(isequal(last_three(x),y_correct))

3   Fail
x = [1.2 3.6 2.5 2.7 2.8 8.6 9.2 2.7 3.7 -4.9]; y_correct = [2.7 3.7 -4.9]; assert(isequal(last_three(x),y_correct))

Index in position 1 exceeds array bounds (must not exceed 1). Error in last_three (line 4) y = x(size(x,2)-3,size(x,2)); Error in Test3 (line 3) assert(isequal(last_three(x),y_correct))
