systmat¶

system matrix

Calling Sequence¶

[Sm]=systmat(Sl);

:Sl linear system ( syslin list) or descriptor system : :Sm matrix pencil :

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]
