There are a couple of crucial errs in your screenshoted code.
(1) In "if" statement condition 2 after && sign "g(ii)" is missing
(2) In "elseif" statement, the same type of err
(3) No need, "else" part. Since no outputs are to be produced
(4) "empty_array" has to have an index, e.g.: empty_array(ii) = g(ii);
