Hi There, In control systems, it is a custom to represent the poles of a transfer function by "X", and the zeros by "o". When, I use mathematica to get the pole-zero plot, I am not sure how to display poles with crosses "x"...the only function I'm aware of is PointSize...but this function uses a different symbol. Is there anybody out there who can propose a straightforward way to do it. Thanks
