Journal of Approximation Theory , () BOOK REVIEWS Book Review Editor: Walter Van Assche Books A. Bultheel and M. Van Barel, Linear Algebra, Rational Approximation and Orthogonal Polynomials, Studies in Computational Mathematics 6, North-Holland Elsevier, Amsterdam, , xvii + pp. Applications. Polynomials can be used to approximate complicated curves, for example, the shapes of letters in typography, [citation needed] given a few points. A relevant application is the evaluation of the natural logarithm and trigonometric functions: pick a few known data points, create a lookup table, and interpolate between those data results in significantly faster.

Reviews: This is the first detailed systematic treatment of (a) the asymptotic behaviour of orthogonal polynomials, by various methods, with applications, in particular, to the ‘classical' polynomials of Legendre, Jacobi, Laguerre and Hermite; (b) a detailed study of expansions in series of orthogonal polynomials, regarding convergence and summability; (c) a detailed study of orthogonal. In mathematics, the Hermite polynomials are a classical orthogonal polynomial sequence.. The polynomials arise in: probability, such as the Edgeworth series;; in combinatorics, as an example of an Appell sequence, obeying the umbral calculus;; in numerical analysis as Gaussian quadrature;; in physics, where they give rise to the eigenstates of the quantum harmonic oscillator;.

Theory and Applications of Numerical Analysis is a self-contained Second Edition, providing an introductory account of the main topics in numerical analysis. The book emphasizes both the theorems which show the underlying rigorous mathematics andthe algorithms which define precisely how to program the numerical methods. In mathematics, an orthogonal polynomial sequence is a family of polynomials such that any two different polynomials in the sequence are orthogonal to each other under some inner product.. The most widely used orthogonal polynomials are the classical orthogonal polynomials, consisting of the Hermite polynomials, the Laguerre polynomials and the Jacobi polynomials together with their .

The outline of this paper is as follows. In Section 2, the current status of the constructive theory of orthogonal polynomials is summarized. General applications of the theory are briefly discussed in Section 3 and various transport-theory applications of nonclassical orthogonal polynomials that have.

Basic tools in this field (orthogonal polynomials, moduli of smoothness, K-functionals, etc.) as well as some selected applications in numerical integration, integral equations, moment-preserving approximation and summation of slowly convergent series are also given.

Beside the basic properties of the classical orthogonal polynomials the book provides new results on nonclassical orthogonal polynomials including methods for their numerical construction.

Orthogonal polynomials are an important example of orthogonal decompositions of Hilbert spaces. They are also of great practical importance: they play a central role in numerical integration using quadrature rules (Chapter 9) and approximation theory; in the context of UQ, they are also a foundational tool in polynomial chaos expansions (Chapter 11).Cited by: 5.
