Chapter 2 provides a quick overview of the theoretical background.
Chapter 3 contains the user guide and description of features.
Chapter 4 provides some real life examples and phase portraits generated using the app.

The app works with limited functionality for versions preceding R2020b. For versions prior to R2020b, mouse click interactions with the plots (adding trajectories and guessing solutions) do not work. All other functionality is retained.

Shoutout to Ameer Hamza and John D'Errico for their witty answers on MATLAB Answers!
