dtsi

stable anti-stable decomposition

Calling Sequence

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

Arguments

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.
