Abstract
We prove a.s. (almost sure) unisolvency of interpolation by continuous random sampling with respect to any given density, in spaces of multivariate a.e. (almost everywhere) analytic functions. Examples are given concerning polynomial and RBF approximation.& COPY; 2023 Elsevier Ltd. All rights reserved.File in questo prodotto:
