I was looking at the functions in the control systems, which were added in V 8, and there seems to be a missing an important plot function to generate automatically a map of the locations of the poles and zeros for a transfer function (continuous or discrete time). Unless I overlooked it, I hope this will be added in V 9. I know I can generate such a plot myself by some extra coding, but I think a build-in function to do this would be a better solution similar to all the other useful standard control systems plot functions listed here http://reference.wolfram.com/mathematica/guide/ClassicalAnalysisAndDesign.html Another software has this function as standard in their control systems toolbox and it is called pzmap (for googling and reference to what this command do). thanks, --Nasser
