The Chebfun Examples have been written by various authors beginning in 2010. New Examples are always welcome!—download ExampleTemplate.m to get started, and if you have a draft, get in touch.

The Examples are updated from time to time, but the original date is retained. That is why, for example, you will sometimes see an example dated in one year referencing a paper from a later year.
