Boolesche zweidimensionale Lagrange-Interpolation

Computing, 1979
Die vorliegende Arbeit liefert eine systematische Anwendung der von Gordon [4], [5] entwickelten Methode der Booleschen Approximation von Funktionen mehrerer Veranderlicher in der zweidimensionalen Lagrange-Interpolation. Es werden Interpolationsmethoden untersucht, deren Interpolationsprojektoren sich als K-fache (K ∈ ℕ) Boolesche Summe von ...

POSITION-DEPENDENT LAGRANGE INTERPOLATING MULTIRESOLUTIONS

International Journal of Wavelets, Multiresolution and Information Processing, 2007
This paper is devoted to the construction of interpolating multiresolutions using Lagrange polynomials and incorporating a position dependency. It uses the Harten's framework21 and its connection to subdivision schemes. Convergence is first emphasized.

New Results on Lagrange Interpolation

1992
Uniform convergence of Lagrange interpolation at zeros of Jacobi polynomials or at the zeros of product Jacobi polynomials, as well as at the zeros of generalized smooth Jacobi polynomials is investigated. We show that by a simple procedure it is always possible to transform the matrices of these zeros into matrices such that the corresponding Lagrange

Lagrange Interpolation in Weighted Besov Spaces

Constructive Approximation, 1999
A function \( w: [-1,1]\rightarrow\mathbb R \) is said to be a generalized Ditzian-Totik weight (GDT weight for short) if \( w \) is of the form \[ w(x):=\prod_{k=0}^M| x-t_k|^{\Gamma_k} \widetilde{w}_k(| t-t_k|^{\delta_k}), \] where \( \Gamma_k\in \mathbb R\), \(-1 ...

On Lattices Admitting Unique Lagrange Interpolations

SIAM Journal on Numerical Analysis, 1977
In this paper generalizations of the classical Lagrange interpolation formula to n-dimensional spaces are discussed. It simplifies and improves upon certain results of some recent authors.

Min-max interpolators and Lagrange interpolation formula

2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003
For oversampled band-limited signals, min-max optimal interpolators have been proposed under assumptions upon either the signal to be interpolated itself (e.g. finite energy) or its Fourier transform. In this paper, we consider the case where the signal is assumed to be bounded.
