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 ...

A Kind of Lagrange Interpolation on the Sphere

2009 WRI World Congress on Computer Science and Information Engineering, 2009
In this paper we deeply research Lagrange interpolation on the unit sphere. First we study the Lagrange interpolation problem along a set of latitudes on the sphere and give three kinds of properly posed sets of nodes along it. Then we get a class of properly posed set of nodes for Lagrange interpolation on the unit sphere by superposition ...

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

On mean convergence of extended Lagrange interpolation

Journal of Computational and Applied Mathematics, 1992
Lagrange interpolation to any continuous function on [-1,1] at the zeros of orthogonal polynomials is known to converge in the mean. Here, following Bellen, we study mean convergence of Lagrange interpolation on an extended set of nodes that includes, in
