Trigonometric interpolation and wavelet decompositions

Numerical Algorithms, 1995
The problem of explicit decomposition and reconstruction algorithms for nested spaces of trigonometric polynomials is studied. The pioneering result connecting multiresolution analysis to nested spaces of trigonometric polynomials is due to \textit{C. K. Chui} and \textit{H. N. Mhaskar} [Constructive Approximation 9, No.

On the trigonometric interpolation and the entire interpolation

Analysis in Theory and Applications, 1990
In this paper, we study a kind of interpolation problems on a given nodal set by trigonometric polynomials of order n and entire functions of exponential type according as the nodal set is $$\left\{ {\frac{{2k\pi }}{n}} \right\}_{k = 0}^{n - 1} or \left\{ {\frac{{2k\pi ...

A discrete trigonometric interpolation method

International Journal of Computer Mathematics, 2001
Interpolation theory is a necessary and crucial tool for many applied engineering sciences. In this paper, we propose a new kind of 2-period interpolation of functions with period 2 pi at the nodes x(k) = x(k),(n) = k pi /n, (k = 0, 1,..., 2n - 1). We find out the necessary and sufficient conditions for regularity of this new interpolation problem ...

Pointwise Estimates of the Trigonometric Interpolation

Acta Mathematica Hungarica, 1997
This paper extends the theme of our article [J. Approximation Theory 77, No. 1, 31-41 (1994; Zbl 0809.41001)] in which we have investigated the remainder of the interpolation of a function \(f\) on a segment \([a,b]\) by algebraic polynomials \(p(f; \cdot )\) at the nodes \(x_i \in [a,b]\) of multiplicity \(r_i\), \(i=1,\dots,n\).
