And, of course, you can eliminate the if...else...end clause easily as well.

disp(['TEST ' char(lbl(all(iswithin(x,lo,hi))+1))])

To avoid the overhead of calling iswithin() twice, save the resulting
logical vector the first time and use it in place of the explicit call...

lbl = {'FAIL';'PASS'};
disp([num2str(x) repmat(' ', [size(x)]) char(lbl(flg+1))])
disp(['TEST ' char(lbl(all(flg)+1))])

NB: One has a choice -- one can eliminate the cast to char() if one
makes the label array a character array instead of cell strings, but
then the subscripting has to use the 2nd dimension ':' to get the full
string, not just the first character. It seems awkward to me there
isn't an overloaded horzcat for cell strings that "just works"...
