Design of a Simple Orthogonal Multiwavelet Filter by Matrix Spectral Factorization

Vasil Kolev, Todor Cooklev, Fritz Keinert

We consider the design of an orthogonal symmetric/antisymmetric multiwavelet from its matrix product filter by matrix spectral factorization (MSF). As a test problem, we construct…

Matrix Spectral Factorization for SA4 Multiwavelet

Vasil Kolev, Todor Cooklev, Fritz Keinert

In this paper, we investigate Bauer's method for the matrix spectral factorization of an r-channel matrix product filter which is a halfband autocorrelation matrix. We regularize t…

Analysis of numerical methods for spectral fractional elliptic equations based on the best uniform rational approximation

Stanislav Harizanov, Raytcho Lazarov, Pencho Marinov +2

Here we study theoretically and compare experimentally an efficient method for solving systems of algebraic equations, where the matrix comes from the discretization of a fractiona…
