Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in sum_of_sec_diag (line 2) y = x(i,i+2)+x(i,i)+i(i+2,i); 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))

Index in position 1 is invalid. Array indices must be positive integers or logical values. Error in sum_of_sec_diag (line 2) y = x(i,i+2)+x(i,i)+i(i+2,i); 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))

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