dtsi Continuous time dynamical systems stable anti-stable decomposition [Ga,Gs,Gi]=dtsi(G,[tol]) G a continuous time linear system. Ga a continuous time linear system antistable and strictly proper. Gs a continuous time linear system stable and strictly proper. Gi real matrix (or polynomial matrix for improper systems) tol 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. syslin pbig psmall pfss 5.4.0 Sl is now checked for continuous time linear dynamical system.
