Journal ArticleDOI
Bivariate Lagrange interpolation at the Padua points: The generating curve approach
TL;DR: To the best of the knowledge, this is the first complete, explicit example of near optimal bivariate interpolation points.
Journal ArticleDOI
Multivariate simultaneous approximation
TL;DR: Theorems of Jackson type are given, for the simultaneous approximation of a function of class Cm and its partial derivatives, by a polynomial and the corresponding partial derivatives as mentioned in this paper.
Journal ArticleDOI
Geometric weakly admissible meshes, discrete least squares approximations and approximate Fekete points
TL;DR: Using the concept of Geometric Weakly Admissible Meshes (see §2 below) together with an algorithm based on the classical QR factorization of matrices, the authors compute efficient points for discrete multivariate least squares approximation and Lagrange interpolation.
Journal ArticleDOI
On certain configurations of points in R n which are unisolvent for polynomial interpolation
TL;DR: In this paper, the authors describe how points may be placed on collections of algebraic varieties so that the resulting system is unisolvent for polynomial interpolation, and give formulas for the corresponding Vandermonde determinants.
