MATLAB Plotting Programs for Bode Diagrams, Nyquist Plots, and Root Locus Diagrams

I have developed custom MATLAB programs for generating Bode diagrams, Nyquist plots, and root locus diagrams. Although these programs are compact and straightforward in design, they offer substantial practical value for teaching analysis and exercise practice. The implementation utilizes MATLAB's control system toolbox functions like bode(), nyquist(), and rlocus() to create accurate visualizations of system frequency response and stability characteristics. Through this development process, I gained significant enjoyment and faced rewarding challenges that enhanced my programming skills and technical knowledge. The programs incorporate features like automatic frequency range selection, stability margin calculations, and customizable plot formatting to improve usability. I hope these tools prove beneficial for users and that others can similarly experience the satisfaction of programming challenges while advancing their coding capabilities through practical control system applications.
