Test Suite

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

2   Pass
x = [1 2 3;4 5 6;7 8 9]; y_correct = [3 6 9;2 5 8;1 4 7]; assert(isequal(rotMatrix(x),y_correct))

3   Fail
x=[1 2 3 4 5;6 7 8 9 0] y_correct = [5 0;4 9;3 8;2 7;1 6]; assert(isequal(rotMatrix(x),y_correct))

x = 1 2 3 4 5 6 7 8 9 0

Unable to perform assignment because the size of the left side is 2-by-5 and the size of the right side is 5-by-2. Error in rotMatrix (line 4) y(end:-1:1,:) = y(:,1:end)'; Error in Test3 (line 3) assert(isequal(rotMatrix(x),y_correct))
