nehari¶

Nehari approximant of continuous time dynamical systems

Calling Sequence¶

[x]=nehari(R [,tol])

: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. :

[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

Version Description 5.4.0 Sl is now checked for continuous time linear dynamical system. This modification has been introduced by this `commit`_ .. _commit: http://gitweb.scilab.org/?p=scilab.git;a=commit;h=3d7083daae3339813ba747c8adcda1f9599bb80d
