contrss

contrss — controllable part

Calling sequence

[slc]=contrss(sl [,tol])

`sl`	: linear system (`syslin` list)
`tol`	: is a threshold for controllability (see `contr`). default value is `sqrt(%eps)`.

returns the controllable part of the linear system sl = (A,B,C,D) in state-space form.



A=[1,1;0,2];B=[1;0];C=[1,1];sl=syslin('c',A,B,C);  //Non minimal
slc=contrss(sl);
sl1=ss2tf(sl);sl2=ss2tf(slc);      //Compare sl1 and sl2
