zeropen - zero pencil

Calling Sequence

[Z,U]=zeropen(Sl)

Parameters

• Sl : a linear system ( syslin list in state-space form [A,B,C,D] )
• Z : matrix pencil Z=s*E-A
• U : square orthogonal matrix

Description

Z = sE - F is the zero pencil of the linear system Sl with matrices [A,B,C,D] . Utility function.

With U row compression of [B;D] i.e, U*[B;D]=[0;*] ; one has:

U*[-sI+A |B;   [ Z |0;      
      C  |D] = [ * |*]
   
    

The zeros of Z are the zeros of Sl .
