 v = cell (expected_nargout, 1);
 [v{:}] = func (...);

it's necessary to pre-allocate the cell array because in the second
line, the number of output values (nargout) should be determined
before func () is called. That is why [v{:}] doesn't work if v doesn't

If you have something else on mind, then please clarify.
