This is a textbook on classical polynomial and rational approximation theory for the twenty-first century. It is aimed at advanced undergraduates and graduate students across all of applied mathematics.

The following are the distinctive features of the book:

  • The emphasis is on topics close to numerical algorithms.
  • Everything is illustrated with Chebfun.
  • Each chapter is a publishable Matlab M-file, available online.
  • There is bias towards theorems and methods for analytic functions, which appear so often in applications, rather than on functions at the edge of discontinuity with their seductive theoretical challenges.
  • Original sources are cited rather than textbooks, and each item in the bibliography is accompanied by an editorial comment.

Keywords: approximation theory, numerical analysis, quadrature, spectral methods

Nick Trefethen is Professor of Numerical Analysis at the University of Oxford and a Fellow of the Royal Society. During 2011-2012 he served as President of SIAM.
