nehari Nehari approximant of continuous time dynamical systems [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). 5.4.0 Sl is now checked for continuous time linear dynamical system. This modification has been introduced by this commit
