obsvss - observable part

### Calling Sequence

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

### Parameters

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

### 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`
