H2 norm of a continuous time proper dynamical system
[n]=h2norm(Sl [,tol])
:Sl continuous time proper linear dynamical system : :n real scalar :
produces the H2 norm of a linear continuous time system Sl.
(For Sl in state-space form h2norm uses the observability gramian and for Sl in transfer form h2norm uses a residue method)
h=`syslin`_('c',(2*0.9*10*s+100)/(s^2+2*0.3*10.1*s+102.01));
h2norm(h)
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
