Gaussian rules on unbounded intervals
نویسندگان
چکیده
A quadrature rule as simple as the classical Gauss formula, with a lower computational cost and having the same convergence order of best weighted polynomial approximation in L is constructed to approximate integrals on unbounded intervals. An analogous problem is discussed in the case of Lagrange interpolation in weighted L norm. The order of convergence in our results is the best in the literature for the considered classes of functions. r 2003 Elsevier Science (USA). All rights reserved.

A Stochastic Algorithm for High Dimensional Integrals over Unbounded Regions with Gaussian Weight
Details are given for a Fortran implementation of an algorithm that uses stochastic spherical-radial rules for the numerical computation of multiple integrals over unbounded regions with Gaussian weight. The implemented rules are suitable for high dimensional problems. A high dimensional example from a computational nance application is used to illustrate the use of the rules.
متن کاملA New Approach to the Quadrature Rules with Gaussian Weights and Nodes
To compute integrals on bounded or unbounded intervals we propose a new numerical approach by using weights and nodes of the classical Gauss quadrature rules. An account of the error and the convergence theory is given for the proposed quadrature formulas which have the advantage of reducing the condition number of the linear system arising when applying Nyström methods to solve integral equati...
متن کاملQuadrature rules on unbounded interval
After some remarks on the convergence order of the classical gaussian formula for the numerical evaluation of integrals on unbounded interval, the authors develop a new quadrature rule for the approximation of such integrals of interest in the practical applications. The convergence of the proposed algorithm is considered and some numerical examples are given.
متن کاملMinimal cubature rules on an unbounded domain
A family of minimal cubature rules is established on an unbounded domain, which is the first such family known on unbounded domains. The nodes of such cubature rules are common zeros of certain orthogonal polynomials on the unbounded domain, which are also constructed. 2000 AMS subject classification: 41A05, 65D05, 65D32.
متن کاملDistributions on matrix moment spaces
In this paper we define distributions on the moment spaces corresponding to p×p real or complex matrix measures on the real line with an unbounded support. For random vectors on the unbounded matricial moment spaces we prove the convergence in distribution to the Gaussian orthogonal ensemble or the Gaussian unitary ensemble, respectively.
