.SH NAME
bstap - hankel approximant
.SH CALLING SEQUENCE
.nf
[Q]=bstap(Sl)

.SH PARAMETERS
.TP 10
sl
: linear system (\fVsyslin\fR list) assumed continuous-time and anti-stable.
.TP
Q
: best stable approximation of \fVSl\fR (\fVsyslin\fR list).
.SH DESCRIPTION
Computes the best approximant \fVQ\fR of the linear system \fVSl\fR

.FI
.LA $$   {\Vert Sl-Q\Vert}_\infty    =  \Vert T \Vert $$
where 
.IG 
||T||
.FI $\Vert T \Vert$ 
is the  H-infinity norm of the Hankel operator associated with \fVSl\fR.
