Hi
It was requested that from a input coefficient vector of size 1 x n+1, where n is the order of the polynomial, get a rlocus plot and compute the Routh Hurwitz. The Routh stabilty creterion is already done, but the problem with my solution for the first item is that it just work if there is a 'K' controller in the input vector, eg: [2 5 9 6+K 8K], but it wont work for [2 5 9 6 8]. However, i just want to get a transfer function ([num],[dem]) from a imput vector like [ a b c d ] that comes from aS^3+bS^2+cS+d .
Thanks.

I'm not sure you can unless you know the gain independently.
For example
and
will both give you the same polynomial,
