routh_tX(1)

NAME
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.
