dtsi

dtsi — stable anti-stable decomposition

Calling sequence

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

`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`

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.
