Chebfun2 is a collection of algorithms that extends Chebfun-like computing to functions of two variables. Chebfun2 represents both scalar and vector-valued functions defined on rectangles. The mathematical basis of the system combines low rank function approximation, 1D Chebyshev technology, and bivariate rootfinding.
The Chebfun2 project is a DPhil research investigation by Alex Townsend under the supervision of Nick Trefethen. The underlying function representations are related to methods developed by Carvajal, Chapman, and Geddes and also others including Bebendorf, Hackbusch, Khoromskij, Oseledets, and Tyrtyshnikov. This software project has led to a short article in SIAM News and is described in detail in an article by Townsend and Trefethen.
