.SH NAME
dtsi - stable anti-stable decomposition
.SH CALLING SEQUENCE
.nf
[Ga,Gs,Gi]=dtsi(G,[tol])
.fi
.SH PARAMETERS
.TP 8
G
: linear system (\fVsyslin\fR list)
.TP
Ga
: linear system (\fVsyslin\fR list) antistable and strictly proper
.TP
Gs
: linear system (\fVsyslin\fR list) stable and strictly proper
.TP
Gi
: real matrix (or polynomial matrix for improper systems)
.TP
tol
: optional parameter for detecting stables poles. Default value: \fV100*%eps\fR
.SH DESCRIPTION
returns the stable-antistable decomposition of \fVG\fR:
.LP
\fVG = Ga + Gs + Gi\fR, \fV(Gi = G(oo))\fR
.LP
\fVG\fR can be given in state-space form or in transfer form.
