routh_t - Routh's table

### Calling Sequence

  `r=routh_t(h [,k]).`

### Parameters

- `h` : square rational matrix

### Description

`r=routh_t(h,k)` computes Routh's table of denominator of the system described by transfer matrix SISO `h` with the feedback by the gain `k` .

If `k=poly(0,'k')` we will have a polynomial matrix with dummy variable `k` , formal expression of the Routh table.
