obsvss

obsvss — observable part

Calling sequence

[Ao,Bo,Co]=obsvss(A,B,C [,tol])  
[slo]=obsvss(sl [,tol])

`A,B,C,Ao,Bo,Co`	: real matrices
`sl,slo`	: `syslin` lists
`tol`	: real (threshold) (default value `100*%eps`)

slo=(Ao,Bo,Co) is the observable part of linear system sl=(A,B,C) (syslin list)

tol threshold to test controllability (see contr); default value = 100*%eps
