A Practical Guide to Pseudospectral Methods
网页Partial differential equations arise in almost all areas of science, engineering, modeling, and forecasting. During the last two decades pseudospectral methods have emerged as successful alternatives to better known computational procedures, (e.g. finite difference and finite element methods of numerical solution), in several key application areas.

Introduction (Chapter 1) - A Practical Guide to Pseudospectral …
网页The connection between spectral methods – in particular the so-called pseudospectral (PS) methods, the topic of this book – and FD methods is closer still. A key theme in this book is to exploit this connection, both to make PS methods more intuitively understandable and to obtain particularly powerful and flexible PS variations.
