rowregul(1) Scilab Function 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).
