ccontrg           Scilab Group           Scilab Function            ccontrg
NAME
   ccontrg - central H-infinity controller
  
CALLING SEQUENCE
 [K]=ccontrg(P,r,gamma);
PARAMETERS
 P    : syslin list (linear system in state-space representation)
      
 r    : 1x2 row vector, dimension of the 2,2 part of P
      
 gamma
       : real number
      
DESCRIPTION
   returns a realization K of the central controller for the general
  standard problem in state-space form.
  
   Note that gamma must be > gopt (ouput of gamitg)
  
   P contains the parameters of plant realization (A,B,C,D) (syslin list)
  with 
  
 B = ( B1 , B2 ) ,        C= ( C1 ) ,    D = ( D11  D12)
                             ( C2 )          ( D21  D22)
   r(1) and r(2) are the dimensions of D22 (rows x columns)
