routh_t

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.
