Is there a way to use bilinear for transforming Digital filter to Analog (NOT ANALOG TO DIGITAL)

So I have an assignment that strictly says:
use bilinear z-transform to transform a digital bandpass filter to analog one.
I have been banging my head on how to do that for about 2 hours now, but it seems like that command can only transform analog to digital and not digital to analog. Any help is much appreciated!

cheb2ord() appears to do the digital to analog transformation as part of its processing, so you might want to examine the code for it.
