zero pencil
[Z, U] = zeropen(Sl)
a linear system (syslin
list in state-space form [A,B,C,D]
)
matrix pencil Z=s*E-A
square orthogonal matrix
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:
The zeros of Z
are the zeros of Sl
.
