Radial quadrature for multiexponential integrands
نویسندگان
چکیده
We introduce a Gaussian quadrature, based on the polynomials that are orthogonal with respect to the weight function ln(2)x on the interval [0, 1], which is suitable for the evaluation of radial integrals. The quadrature is exact if the non-Jacobian part of the integrand is a linear combination of a geometric sequence of exponential functions. We find that the new scheme is a useful alternative to existing approaches, particularly for integrands that exhibit multiexponential behavior.

An Improved Bayesian Framework for Quadrature of Constrained Integrands
Quadrature is the problem of estimating intractable integrals, a problem that arises in many Bayesian machine learning settings. We present an improved Bayesian framework for estimating intractable integrals of specific kinds of constrained integrands. We derive the necessary approximation scheme for a specific and especially useful instantiation of this framework: the use of a log transformati...
متن کاملVectorized Adaptive Quadrature in Matlab
Adaptive quadrature codes process a collection of subintervals one at a time. We show how to process them all simultaneously and so exploit vectorization and the use of fast built-in functions and array operations that are so important to efficient computation in Matlab. Using algebraic transformations we have made it just as easy for users to solve problems on infinite intervals and with moder...
متن کامل1 Obtaining O ( N − 2 + ǫ ) Convergence for Lattice Quadrature Rules ⋆ Fred
Abstract. Good lattice quadrature rules are known to have O(N) convergence for periodic integrands with sufficient smoothness. Here it is shown that applying the baker’s transformation to lattice rules gives O(N) convergence for nonperiodic integrands with sufficient smoothness. This approach is philosophically and practically different than making a periodizing transformation of the integrand,...
متن کاملUsing Chebyshev polynomial’s zeros as point grid for numerical solution of nonlinear PDEs by differential quadrature- based radial basis functions
Radial Basis Functions (RBFs) have been found to be widely successful for the interpolation of scattered data over the last several decades. The numerical solution of nonlinear Partial Differential Equations (PDEs) plays a prominent role in numerical weather forecasting, and many other areas of physics, engineering, and biology. In this paper, Differential Quadrature (DQ) method- based RBFs are...
متن کاملOptimal quadrature for Haar wavelet spaces
This article considers the error of the scrambled equidistribution quadrature rules in the worst-case, random-case, and average-case settings. The underlying space of integrands is a Hilbert space of multidimensional Haar wavelet series, Hwav . The asymptotic orders of the errors are derived for the case of the scrambled (λ, t,m, s)-nets and (t, s)-sequences. These rules are shown to have the b...
