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
andYT
and the poles ofn
andM
(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.
