Multidimensional Adaptive Quadrature Over Simplices
The objective of this work is the development of novel, efficient and reliable multidimensional adaptive quadrature routines defined over simplices (MAQS). MAQS provides an approximation to the integral of a function defined over the unit hypercube and provides an error estimate that is used to drive a global subdivision strategy. The quadrature estimate is based on Lagrangian interpolation def...
متن کاملQuadrature Estimates for Multidimensional Integrals
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 ...
متن کاملHierarchical quadrature for multidimensional singular integrals
We introduce a method for the evaluation of singular integrals arising in the discretisation of integral equations. The method is based on the idea of repeated subdivision of domains. The integrals defined on these subdomains are classified. Each class can be expressed as a sum of regular integrals and representatives of other classes. A system of equations describes the relations between the c...
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 کاملReliability Conditions in Quadrature Algorithms
The detection of insu ciently resolved or ill-conditioned integrand structures is critical for the reliability assessment of the quadrature rule outputs. We discuss a method of analysis of the pro le of the integrand at the quadrature knots which allows inferences approaching the theoretical 100% rate of success, under error estimate sharpening. The proposed procedure is of the highest interest...
