des2tf(1)

NAME
des2tf - descriptor to transfer function conversion

CALLING SEQUENCE
[S]=des2tf(sl)
[Bfs,Bis,chis]=des2tf(sl)

PARAMETERS

sl  : list (linear system in descriptor form)

Bfs, Bis
    : two polynomial matrices

chis
    : polynomial

S   : rational matrix

DESCRIPTION
Given the linear system in descriptor form i.e. Sl=list('des',A,B,C,0,E), des2tf converts sl into its transfer function representation:
S=C*(s*E-A)^(-1)*B
Called with 3 outputs arguments des2tf returns Bfs and Bis two polynomial matrices, and chis polynomial such that:
S=Bfs/chis - Bis
chis is the determinant of (s*E-A) (up to a xcative constant);
