Error: Invalid expression. Check for missing multiplication operator, missing or unbalanced
delimiters, or other syntax error. To construct matrices, use brackets instead of parentheses.

If you are reading a 2's complement hex pattern for a known sized integer, you can just use the simple test you proposed. You could of course typecast the result into a signed integer and then check the sign, but it will give you the same result as the simple test you proposed. If you actually need the value, then just:
u = the unsigned uint16 number
s = typecast(u,'int16'); % the signed int16 number with same bit pattern as u
