### AMATH481: LECTURE M 12/05 (QUIZ)

Note: This post is part of my scientific computing course (UW AMATH481) in autumn 2016. The course web page is here.

In this lecture, we began discussing the implementation of spectral methods for ODEs using collocation at Chebyshev nodes. The material corresponds to Chapter 21 of “Approximation Theory and Approximation Practice”, which is not freely available (though much of it is contained in ch21.m which can be downloaded here).

You can download the sketches and code from lecture here. For the code to run, be sure that you have downloaded Chebfun and have added the chebfun directory to your path. See the directions here.

This lecture included the fifth and final quiz. The subject of the quiz was the Lagrange interpolating idea, in its various forms. You can download the quiz and its solution here
