I'm trying to prooduce a plot of a root locus for an open loop transfer function. The transfer function is in the z-domain, with a gain K. I've already solved for the charectoristic equation of the system by hand. But, how do I use Matlab to plot the root locus of a transfer function in the Z - Domain? I've seen examples in the Laplace (s) Domain...do these work the same way? (as in...i won't need to do anything differently?) thank you.
