copfac

right coprime factorization

Calling Sequence

[N,M,XT,YT]=copfac(G [,polf,polc,tol])

Arguments

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.
