sm2des - system matrix to descriptor

Calling Sequence

[Des]=sm2des(Sm);

Parameters

• Sm : polynomial matrix (pencil system matrix)
• Des : descriptor system ( list('des',A,B,C,D,E) )

Description

Utility function: converts the system matrix:

 Sm = [-sE + A   B;
      [    C     D]
   
    

to descriptor system Des=list('des',A,B,C,D,E) ).
