rowregul(1)

NAME
rowregul - removing poles and zeros at infinity

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

PARAMETERS

Sl,Stmp
    : syslin lists

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

DESCRIPTION
computes a postfilter Ws such that Stmp=Ws*Sl 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 right invertible linear system (syslin list) in state-space representation with possibly a polynomial D matrix.

This function is the dual of colregul (see function code).
