End conditions for interpolatory quintic splines [PDF]

open access: yes, 1980
Accurate end conditions are derived for quintic spline interpolation at equally spaced knots. These conditions are in terms of available function values at the knots and lead to 0(h6) covergence uniformly on the interval of ...

The Penalized Lebesgue Constant for Surface Spline Interpolation

open access: yes, 2010
Problems involving approximation from scattered data where data is arranged quasi-uniformly have been treated by RBF methods for decades. Treating data with spatially varying density has not been investigated with the same intensity, and is far less well

Towards a More General Type of Univariate Constrained Interpolation With Fractal Splines

open access: yes, 2015
Recently, in [Electronic Transaction on Numerical Analysis, 41 (2014), pp. 420-442] authors introduced a new class of rational cubic fractal interpolation functions with linear denominators via fractal perturbation of traditional nonrecursive rational ...

Equation of state SAHA-S meets stellar evolution code CESAM2k

open access: yes, 2017
We present an example of an interpolation code of the SAHA-S equation of state that has been adapted for use in the stellar evolution code CESAM2k. The aim is to provide the necessary data and numerical procedures for its implementation in a stellar code.

Multipatch Approximation of the de Rham Sequence and its Traces in Isogeometric Analysis

open access: yes, 2019
We define a conforming B-spline discretisation of the de Rham complex on multipatch geometries. We introduce and analyse the properties of interpolation operators onto these spaces which commute w.r.t. the surface differential operators.

Toward an Iterative Algorithm for Spline Interpolation [PDF]

open access: yes, 1993
One of the fundamental results in spline interpolation theory is the famous Schoenberg-Whitney Theorem, which completely characterizes those distributions of interpolation points which admit unique interpolation by splines.

Vector-valued Lg-splines I. Interpolating splines

open access: yesJournal of Mathematical Analysis and Applications, 1979
AbstractThe theory of Lg-splines developed by Jerome and Schumaker is extended to the vector-valued (multivariate) case. The extension is described in the frame-work of a reproducing-kernel Hilbert space which among other things allows the establishment of a congruent least-squares estimation problem for a vectorvalued lumped random process.

Quadratic spline interpolation with coinciding interpolation and spline grids

open access: yesJournal of Computational and Applied Mathematics, 1982
The authors consider the problem of quadratic spline interpolation of continuous functions in the case when the spline grid and the interpolation grid coincide. The main purpose of the paper is to deduce error estimations for the quadratic spline function s interpolating a given function f on a grid with width h.
