copfac - right coprime factorization
Calling Sequence
- [N,M,XT,YT]=copfac(G [,polf,polc,tol])
Parameters
-
G: syslin list (continuous-time linear system )
-
polf, polc: respectively the poles of XT and YT and the poles of n and M (default values =-1).
-
tol: real threshold for detecting stable poles (default value 100*%eps)
-
N,M,XT,YT: linear systems represented by syslin lists
Description
[N,M,XT,YT]=copfac(G,[polf,polc,[tol]]) returns a right coprime factorization of G.
G = N*M^-1 where N and M are stable, proper and right coprime.
(i.e. [N M] left-invertible with stability)
XT and YT satisfy:
[XT -YT].[M N]' = eye (Bezout identity)
G is assumed stabilizable and detectable.
