Web14 jul. 2024 · [Higham, Matrix Nearness Problems and Applications, Th. 4.1] does provide a positive answer to Question 1, and even a partial answer to Question 3. However, it does not contain any proof or reference for this theorem. Even though the author is quite trustworthy, I dare not rely on solely such a reference.
WebIn this paper we introduce a new matrix nearness problem that is intended to generalize the distance to instability. Due to its applicability in analyzing the robustness of eigenvalues with respect to the arbitrary localization sets (domains) in the complex plane, we call it the distance to delocalization. small food masherWebThe matrix nearness problems have many applications especially in finance, statistics, and compressive sensing. For example, one application in statistics is to make adjustments to a symmetric matrix so that it is consistent with prior knowledge or assumptions, and is a valid covariance matrix [ 3 – 8 ]. songs in christmas moviesWeb11 apr. 2024 · How the Falcons can reclaim the NFL career of former Lions top pick Jeff Okudah.
