  In this paper we introduce the notion of cyclic ($f(t),\sigma,\delta$)-codes
for $f(t)\in \Ore$. These codes generalize the $\theta$-codes as introduced by
D. Boucher, F. Ulmer, W. Geiselmann \cite{BGU}. We construct generic and
control matrices for these codes. As a particular case the ($\si,\de$)-$W$-code
associated to a Wedderburn polynomial are defined and we show that their
control matrices are given by generalized Vandermonde matrices. All the
Wedderburn polynomials of $\mathbb F_q[t;\theta]$ are described and their
control matrices are presented. A key role will be played by the pseudo-linear
transformations.
