balreal           Scilab Group           Scilab Function            balreal
NAME
   balreal - balanced realization
  
CALLING SEQUENCE
 [slb [,U] ] = balreal(sl)
PARAMETERS
 sl,slb
       : linear systems (syslin lists)
      
DESCRIPTION
   Balanced realization of linear system sl=[A,B,C,D]. sl can be a
  continuous-time or discrete-time state-space system.  sl is assumed
  stable.
  
 slb=[inv(U)*A*U ,inv(U)*B , C*U , D]
   is the balanced realization.
  
   slb is returned as a syslin list.
  
EXAMPLE
 A=diag([-1,-2,-3,-4,-5]);B=rand(5,2);C=rand(1,5);
 sl=syslin('c',A,B,C);
 [slb,U]=balreal(sl);
 Wc=clean(ctr_gram(slb))
 W0=clean(obs_gram(slb))
