Quadrature Estimates for Multidimensional Integrals

چکیده
We prove estimates for the error in the most straightforward discrete approximation to the integral of a compactly supported function of n variables. The methods use Fourier analysis and interpolation theory, and also make contact with classical lattice point estimates. We also prove error estimates for the approximation of the integral over an interval by the trapezoidal rule and the midpoint rule.

Application of CAS wavelet to construct quadrature rules for numerical integration
In this paper, based on CAS wavelets we present quadrature rules for numerical solution of double and triple integrals with variable limits of integration. To construct new method, first, we approximate the unknown function by CAS wavelets. Then by using suitable collocation points, we obtain the CAS wavelet coefficients that these coefficients are applied in approximating the unk...
متن کاملParallel Components for Multidimensional Quadrature: Some Experiences
In this paper we present our experiences in wrapping a parallel multidimensional quadrature routine, based on the BLACS message-passing library, in order to obtain a software component computing multiple multidimensional integrals. The reference framework, where the component lives, is a programming environment called ASSIST, under development in the context of Italian research projects, which ...
متن کاملComposite quadrature formulae for the approximation of wavelet coefficients of piecewise smooth and singular functions
The computation of wavelet coefficients of a function typically requires the computation of a large number of integrals. These integrals represent the inner product of that function with a wavelet function on different scales, or with the corresponding scaling function on a fine scale. We develop quadrature rules for those integrals that converge fast for piecewise smooth and singular functions...
متن کاملError estimates with explicit constants for Sinc approximation, Sinc quadrature and Sinc indefinite integration
Error estimates with explicit constants are given for approximations of functions, definite integrals and indefinite integrals by means of the Sinc approximation. Although in the literature various estimates have already been given for these approximations, they were basically for examining the rates of convergence, and several constants were left unevaluated. Giving more explicit estimates, i....
