It is not a function I use a lot, but it seems like the zpk view of linear systems in NamedStateSpace structure does not work. tf does work.

tf
test = ss([-1 2 3; 0 -2 3; 0 0 -3],[1;2;3],[1 2 3], [0.0]) tf(test) tf(named_ss(test)) zpk(test)
This works (however, tf does not work if all numbers are integers -- e.g., if the D-matrix of test is set to [0], tf fails.).
test
[0]
The following does not work:
zpk(named_ss(test))
Thanks for the issue, it's closed by #847 and https://github.com/JuliaControl/ControlSystems.jl/commit/20365704630380bc739f134c0ffa379009999459
