Spectral Methods : Algorithms, Analysis and Applications

Along with finite differences and finite elements, spectral methods are one of the three main methodologies for solving partial differential equations on computers.

This book provides a detailed presentation of basic spectral algorithms, as well as a systematical presentation of  basic convergence theory and error analysis for spectral methods.

Readers of this book will be exposed to a unified framework for designing and analyzing spectral algorithms for a variety of problems, including in particular high-order differential equations and problems in unbounded domains.

The book contains a large number of figures which are designed to illustrate various concepts stressed in the book.

A set of basic matlab codes has been made available online to help the readers to develop their own spectral codes for their specific applications.
