colregul(1)

NAME
colregul - removing poles and zeros at infinity

CALLING SEQUENCE
[Stmp,Ws]=colregul(Sl,alfa,beta)

PARAMETERS

Sl,Stmp
    : syslin lists

alfa,beta
    : reals (new pole and zero positions)

DESCRIPTION
computes a prefilter Ws such that Stmp=Sl*Ws is proper and with full rank D matrix.

Poles at infinity of Sl are moved to alfa;

Zeros at infinity of Sl are moved to beta;

Sl is a assumed to be a left invertible linear system (syslin list) in state-space representation with possibly a polynomial D matrix.
