### Test Suite

Test Status Code Input and Output
1   Fail
x = magic(6); y_correct = 111; assert(isequal(sum_of_sec_diag(x),y_correct))

Matrix dimensions must agree. Error in sum_of_sec_diag (line 2) sum(sum(fliplr(x).*eye(3))) Error in Test1 (line 3) assert(isequal(sum_of_sec_diag(x),y_correct))

2   Fail
x = magic(10); y_correct = 505; assert(isequal(sum_of_sec_diag(x),y_correct))

Matrix dimensions must agree. Error in sum_of_sec_diag (line 2) sum(sum(fliplr(x).*eye(3))) Error in Test2 (line 3) assert(isequal(sum_of_sec_diag(x),y_correct))

3   Fail
x = magic(11); y_correct = 671; assert(isequal(sum_of_sec_diag(x),y_correct))

Matrix dimensions must agree. Error in sum_of_sec_diag (line 2) sum(sum(fliplr(x).*eye(3))) Error in Test3 (line 3) assert(isequal(sum_of_sec_diag(x),y_correct))

4   Fail
x=[1 2 3; 4 4 6; 2 8 9]; y_correct = 9; assert(isequal(sum_of_sec_diag(x),y_correct))

ans = 9

Output argument "and" (and maybe others) not assigned during call to "sum_of_sec_diag". Error in Test4 (line 3) assert(isequal(sum_of_sec_diag(x),y_correct))
