Matlab programs

  1. For your reference, here are my programs for Euler's method and Euler's improved method. Notice that one uses a predefined function, while the other yas the function directly coded into the method.
  2. The MATLAB function file for the Lorenz system.
  3. Programs to assess the accuracy of ode45: Oscillator and Lorenz system.

Lab information

A lot of information on the lab we will use for the class can be found on the Calclab Home Page. Please refer to the information there first for any technical question.

Please, refer also to the current help page.

MATLAB information

The software Matlab will be used in this class in order to avoid extensive hand calculations and to elucidate important concepts. It is a standard software for mathematical computations at universities and in industry.

Please have MATLAB set up on your calclab account for the second class (Wed, Aug 29). Extensive information on the setup process can be found on Art Belmonte's Home Page. In Calclab, use the Linux setup. You can also use the setup at home; just select the suitable operating system option there.

Make sure your have a look at Dr. Belmonte's streaming videos explaining the setup process and assisting you in a lot of ways.
