Extended cubic uniform B-splineShape parameterConvergence rateSpectral radiusIn this paper, we concern with the data interpolation by using extended cubic uniform B-splines with shape parameters. Two iterative formats, namely the progressive iterative approximation (PIA) and the weighted progressive ...
Let f ∈ H1(Dδ), h > 0, and M∈N0 be given. If (3.7)|f(ξ)|≤Cexp(−b|ξ|) for all ξ∈R with b,C>0,then the quadrature error satisfies ∫Rf(ξ)dξ−TM(f,H)≤Ce−2πδbM with h=2πδ/bMand with a positive constant C depending only on f, δ, b (cf. ...
In this paper we give precise values of the norms of projection operators of inter-polation by periodic trigonometric splines of order one with equidistant knots. The ap-proach is different from the previous ones and can be extended to the case of higherorders.翁祖荫...

摘要: We give sufficient conditions which guarantee that a set of points admits unique Lagrange interpolation by quadratic splines on a four-directional mesh. The poisedness of these sets will be proved by reducing one bivariate problem to a finite sequence of univariate problems....
