On Product Integration With Gauss-Kronrod Nodes

open access: yes, 1998
. Gauss-Kronrod product quadrature formulas for the numerical approximation of R 1 \Gamma1 k(x)f(x)dx are shown to converge for every Riemann integrable f , and to possess optimal stability. Similar results are proved for the product formulas based on

Constructing embedded lattice rules for multivariate integration

open access: yes, 2006
. Lattice rules are a family of equal-weight cubature formulas for approximating highdimensional integrals. By now it is well established that good generating vectors for lattice rules having n points can be constructed component-by-component for ...

POLYNOMIAL HISTOPOLATION, SUPERCONVERGENT DEGREES OF FREEDOM, AND PSEUDOSPECTRAL DISCRETE HODGE OPERATORS

open access: yes, 2008
. We show that, given a histogram with n bins—possibly non-contiguous or consisting of single points—there exists a unique polynomial histopolant (polynomial of order n with bin averages equal to the histogram’s).
