systmat(1)                     Scilab Function                     systmat(1)
NAME
  systmat - system matrix

CALLING SEQUENCE
  [Sm]=systmat(Sl);

PARAMETERS

  Sl   : linear system (syslin list) or descriptor system

  Sm   : matrix pencil

DESCRIPTION
  System matrix of the linear system Sl (syslin list) in state-space form
  (utility function).
   Sm = [-sI + A   B;
        [    C     D]
  For a descriptor system (Sl=list('des',A,B,C,D,E)), systmat returns:
   Sm = [-sE + A   B;
        [    C     D]
