I think there is a bug in dtedtile.m:

% use sign bit to identify values which should be negative
id_neg = find(bitand(map,32768)==32768); % create list of indices of values to convert to negatives
%map(id_neg) = -map(id_neg); % this is incorrect original. should clear sign bit then negate.
map(id_neg) = -( bitand(map(id_neg), 32767));
