Numerical cubature on scattered data by adaptive interpolation
Published 14 Jul 2023 in math.NA and cs.NA | (2307.07203v1)
Abstract: We construct cubature methods on scattered data via resampling on the support of known algebraic cubature formulas, by different kinds of adaptive interpolation (polynomial, RBF, PUM). This approach gives a promising alternative to other recent methods, such as direct meshless cubature by RBF or least-squares cubature formulas.
