What's the difference between this question and the question I answered before?

Honglei has a very good point. You should go back and accept Honglei's original answer.

You have not given us your desired peak-to-peak ripple or passband edge frequency or sampling frequency, but the general idea is something like this:

   for orders = 2:4
    [B{orders-1},A{orders-1}] = cheby1(orders,0.5,0.25);
   end
   fvtool(B{1},A{1},B{2},A{2},B{3},A{3})
