how increment a name of a variable?

Hi I have a lot of matricies A1, A2, A3, etc etc and they have same size. I would to use command horzcat for have a unic big matrix

    if true
    % A=horzcat(A1,A1,A3,.....)
    end

If I don't want to write all name of matricies but I want to increment the number near the A, what can I do?
