1   Fail
x = 1; y_correct = 1; assert(isequal(sum_diag(x),y_correct))

Index in position 1 exceeds array bounds (must not exceed 1). Error in sum_diag (line 2) y = x(1,1)+x(2,2)+x(3,3); Error in Test1 (line 3) assert(isequal(sum_diag(x),y_correct))

2   Pass
x = eye(3); y_correct = 3; assert(isequal(sum_diag(x),y_correct))

3   Pass
x = magic(3); y_correct = 15; assert(isequal(sum_diag(x),y_correct))
