Orthogonal polynomials: Applications and computation. (English) Zbl 0871.65011
Iserles, A. (ed.), Acta Numerica Vol. 5, 1996. Cambridge: Cambridge University Press. 45-119 (1996).
This is an extended survey paper on recent work on orthogonal polynomials and their application in interpolation, approximation and quadrature. It contains many details and excellent references to recent (and older) literature and information on available software. Among the subjects treated are a motivational introduction based on Gauss-type quadrature rules, computation of the coefficients in the three-term recurrence relation, rational interpolation, constrained least squares approximation, slowly convergent infinite series, moment-based methods, and Sobolev orthogonal polynomials (if derivatives are also to be approximated). The paper is a reference not to be missed by anyone seriously interested in the subject.
