Scilab Function

dtsi - stable anti-stable decomposition

### Sequence d'appel

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

### Parametres

- `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.
