dtsi(1)

NAME
dtsi - stable anti-stable decomposition

CALLING SEQUENCE
[Ga,Gs,Gi]=dtsi(G,[tol])

PARAMETERS

G   : linear system (syslin list)

Ga  : linear system (syslin list) antistable and strictly proper

Gs  : linear system (syslin list) stable and strictly proper

Gi  : real matrix (or polynomial matrix for improper systems)

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

DESCRIPTION
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.
