rowregul Scilab Group Scilab Function rowregul
NAME
rowregul - removing poles and zeros at infinity
CALLING SEQUENCE
[Stmp,Ws]=rowregul(Sl,alfa,beta)
PARAMETERS
Sl,Stmp : syslin lists
alfa,beta : real numbers (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).
EXAMPLE
s=%s;
w=[1/s,0;s/(s^3+2),2/s];
Sl=tf2ss(w);
[Stmp,Ws]=rowregul(Sl,-1,-2);
Stmp('D') // D matrix of Stmp
clean(ss2tf(Stmp))
SEE ALSO
