systmat

Arguments

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]
