Name
nehari — Nehari approximant
Calling Sequence
[x]=nehari(R [,tol])
Parameters
- R
linear system (syslin list)
- x
linear system (syslin list)
- tol
optional threshold
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
