Polynomial approximation constitutes a fundamental framework in numerical analysis and applied mathematics, where complex functions are represented by simpler polynomial forms. A central pillar of ...

Structured low-rank approximation (SLRA) is a mathematical framework that seeks to approximate a given data matrix by another matrix of lower rank while preserving intrinsic structural properties.

In the present work, we aim to study the rate of convergence of Jacobi polynomial using characterized Hausdorff matrix. Another important aim of the present work is to estimate the wavelet ...
