nehari
Nehari approximant of continuous time dynamical systems
Calling Sequence
[x]=nehari(R [,tol])
Arguments
- R
a continuous time linear dynamical system in state-space representation.
- x
a continuous time linear dynamical system in state-space representation.
- tol
optional threshold, default value is 1e-6.
Description
[x]=nehari(R [,tol])returns the Nehari approximant of R.
R = linear system in state-space representation (syslin list).
R is strictly proper and - R~ is stable
(i.e. R is anti stable).
|| R - X ||oo = min || R - Y ||oo Y in Hoo
