Trefethen: Spectral Methods in MATLAB

What changed

Packaged forty concise MATLAB examples into a computational spectral-method teaching framework.

Scientific scope

The record is Trefethen’s sole-author 2000 SIAM book. Spectral methods have earlier lineages, the book omits some later-standard tools such as barycentric interpolation, and its programs are demonstrations rather than universal numerical solvers.
