Abstract

I have recently been working on verified numerical computation for eigenvalues of matrices.The eigenvalues of matrices obtained by numerical calculations contain various errors, and their accuracy is often unknown.In some application fields, the accuracy of all eigenvalues is essential, and the proposed method can evaluate the accuracy of eigenvalues rigorously.In this presentation, we will present a fast and portable verification method.
