ValidInputs = {'AB', 'BC', 'CD', 'DE', 'AD'};
INPUT = input('enter some letters', 's');
[found, idx] = ismember(lower(INPUT), lower(ValidInputs) );
if ~found
error('invalid input');
end
selected_case_idx = idx;
selected_case = ValidInputs{selected_case_idx};

Try this:
validInputs = {'AB', 'BC', 'CD', 'DE', 'AD'};
selectedIndex = listdlg("PromptString",'Select an option', 'ListString', validInputs)
fprintf('You selected index %d which is %s.\n', selectedIndex, validInputs{selectedIndex});
