double coprime factorization



Calling Sequence
~~~~~~~~~~~~~~~~


::

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




Arguments
~~~~~~~~~

: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.
