As per my understanding you want to plot poles and zeros for a signal.You can use matlab inbuilt function zplane to plot poles and zeros of discrete time signal in MATLAB.
Please refer the following documentation on how to use zplane:
Zero-pole plot for discrete-time systems - MATLAB zplane - MathWorks India
