Clean way to find which elements of categorical array are part of a set of labels

Hi. I have a categorical array. I want to find which elements belong to a set of labels. Here is an example of what I would like to write, but I obviously need some form of function here.

data = nominal( {'a', 'b', 'c', 'b', 'a'} )'

%This line will in fact not work, so I am looking for a clean way to write it.
isAorB = any(data == {'a', 'b'});

disp( isAorB );

I think you are looking for this:

data = {'a', 'b', 'c', 'b', 'a'} ;
members = {'a','b'};

ismember(data,members)

ans =

       1     1     0     1     1
