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:

      [    C     D]
