Lecture Note Supplements

Chapter 2: Programming Supplement

A class demonstration of Maple and MatLab is given for the one-dimensional heat equation. Links are provided to computer code for Maple (heat1d (PDF)) and MatLab (heatjm.m) for the Heat Equation in one-dimension.

Chapter 3: Programming Supplement

A class demonstration of a Fourier series is given. A link is provided for a MatLab M-file for this Fourier series.

Chapter 5: Programming Supplement

Finding eigenvalues for boundary conditions of the third kind . A link is provided for a Maple file to show how to numerically find eigenvalues of this transcendental equation.

Chapter 7: Programming Supplement

Visualizing vibrating rectangular membranes, we have a link for a Maple file (rect_memb.mws). Also, solutions to Bessel's differential equation are provided using Maple (bessel.mws) and a hyperlink to Maplesoft and others. Solutions to Legendre's differential equation are provided using Maple (legendre.mws).


Below are some MatLab codes and pictures from PDEs provided by Ricardo Carretero.
