Python code used for instruction of AMATH 351 (Intro to DIffEqs) at the University of Washington.
The folder titled hw_plots contains Jupyter Notebooks (.ipynb) intended to help students plot solutions for various homework assignments. These are meant for students who have had minimal or no experience with numerical plotting of functions (e.g., NumPy/PyPlot, MATLAB, etc.).
The folder titled phase_plane contains the files (Jupyter notebooks, one helper .py file) used for a demonstration on numerical construction of phase portraits for 2D autonomous systems. In this folder, the file pplane_demo.ipynb provides the template for the live demo (to be filled in during class), and the file pplane_demo_complete.ipynb contains the full version of the demo (i.e., what you would fill the template file in with). This demo uses the toggle switch system as a motivating example. The file pplane.ipynb demonstrates a version of the demo code written for any 2D autonomous system (examples include toggle switch with different parameter values and Lotka-Volterra system), the main code for which is contained in the file pplane.py.
