observable part



Calling Sequence
~~~~~~~~~~~~~~~~


::

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




Arguments
~~~~~~~~~

:A,B,C,Ao,Bo,Co real matrices

Description
~~~~~~~~~~~

`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`
