dcf - double coprime factorization

### Sequence d'appel

  `[N,M,X,Y,NT,MT,XT,YT]=dcf(G,[polf,polc,[tol]])`

### Parametres

- `G` : `syslin` list (continuous-time linear system)
- `polf, polc` : respectively the poles of `XT` and `YT` and the poles of `N` and `M` (default values =`-1`).
- `tol` : real threshold for detecting stable poles (default value `100*%eps`).
- `N,M,XT,YT,NT,MT,X,Y` : linear systems represented by `syslin` lists

### Description

returns eight stable systems `(N,M,X,Y,NT,MT,XT,YT)` for the doubly coprime factorization

`G` must be stabilizable and detectable.
