Continuous time dynamical systems stable anti-stable decomposition

Calling Sequence




a continuous time linear system.


a continuous time linear system antistable and strictly proper.


a continuous time linear system stable and strictly proper.


real matrix (or polynomial matrix for improper systems)


optional parameter for detecting stables poles. Default value: 100*%eps


returns the stable-antistable decomposition of G:

G= Ga + Gs + Gi, (Gi = G(oo))

G can be given in state-space form or in transfer form.

Ga and Gs are returned in the same representation (transfer function or state-space) than G.
