Forward and Backward approximation in c2d

Hello,

I would like to change my transfer function from continuous to discrete using the forward and backward derivative approximation. Is there an easy way to do this? I've found "bilin" function, but it didn't work the way, I supposed it will... Maybe a symbolic equivalency? s = (z - 1)/T ?

Thank You!
