Name
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.
