No single line command, but
largest_val = (-min(x) < max(x))*(max(x)-min(x))+min(x);
is cheeky and it preserves the sign.

Not sure if
counts as single command for you...

"I should not" because of a good technical reason or just because someone told you / this is part of a homework? I can think of sorting the values first and then take the largest of the (1) and (end) values.

You need the "maximum value". Then there is no reason for ABS, but you can call simply:
result = max(x)
