App for Control Calculator for Beginners

This GUI provides results from a step input, impulse input and diagrams of Root Locus, Bode, and Nyquist. It is very simple to use; just fill out transfer function based on pole, zero, gain, then click 'calculate' button. You can see multi-results of the transfer function you insert. In addition, This code shows a math equation of the transfer function on the figure. Furthermore, you can see zoom in/out on the figure by using 'max' button.

When I was preparing a qualifying exam, I wanted to easily/quickly see and check the results from Root Locus, Bode, and Nyquist based on the transfer function. it was very useful to understand about them. Please enjoy :)
