Refinement masks of Hurwitz type in the cardinal interpolation problem
نویسنده
چکیده
Riassunto: Si studiano le proprietà di una particolare classe di funzioni di raffinamento simmetriche, a supporto compatto e totalmente positive. Si dimostra che tali funzioni di raffinamento possono essere usate nel problema dell’interpolazione cardinale generalizzata poiché esiste un unico valore eccezionale che viene qui calcolato esattamente. Vengono presentati alcuni esempi numerici riguardanti l’interpolazione e la costruzione di wavelets semi-ortogonali tramite tali funzioni di raffinamento.

gH-differentiable of the 2th-order functions interpolating
Fuzzy Hermite interpolation of 5th degree generalizes Lagrange interpolation by fitting a polynomial to a function f that not only interpolates f at each knot but also interpolates two number of consecutive Generalized Hukuhara derivatives of f at each knot. The provided solution for the 5th degree fuzzy Hermite interpolation problem in this paper is based on cardinal basis functions linear com...
متن کاملCover interpolation functions and h-enrichment in finite element method
This paper presents a method to improve the generation of meshes and the accuracy of numerical solutions of elasticity problems, in which two techniques of h-refinement and enrichment are used by interpolation cover functions. Initially, regions which possess desired accuracy are detected. Mesh improvment is done through h-refinement for the elements existing in those regions. Total error of th...
متن کاملA new class of bivariate refinable functions suitable for cardinal interpolation
In this paper a new class of bivariate refinable functions is constructed by means of the directional convolution product between the tensor product of two univariate refinable functions belonging to a particular class, shortly recalled in this paper, with a third one in the same class. The new functions have many properties useful in applications, such as compact support, positivity, central s...
متن کاملOptimal Interpolatory Subdivision Schemes in Multidimensional Spaces * Bin Han † and Rong-qing Jia ‡
We analyse the approximation and smoothness properties of fundamental and refinable functions that arise from interpolatory subdivision schemes in multidimensional spaces. In particular, we provide a general way for the construction of bivariate interpolatory refinement masks such that the corresponding fundamental and refinable functions attain the optimal approximation order and smoothness or...
