The eigenvalues of a matrixAare found by solving the characteristic equation: det(A−λI)=0 WhereIis the identity matrix of the same size asA. How to Calculate Eigenvalues and Eigenvectors The process involves the following steps: Step 1: Write down the matrixA. ...
The standard eigenvector computation is recovered by setting $\\mathbf{B}$ to an identity matrix. Our analysis reduces the dependence on the eigengap, making it the first Riemannian eigensolver that achieves the optimal rate. Experiments demonstrate that the proposed search method is able to ...

An eigenproblem solver, eigb, is easy to build using the algorithms developed in the book. First, reduce matrix A to upper Hessenberg form H = PTAP and compute the eigenvalues by applying the Francis double-shift QR iteration to H. Now find corresponding eigenvectors of H using inverse itera...

Based on a decomposition of 2-D covariance matrix and by using a signal-eigenvector-smoothing technique, the directions of arrival and the center frequencies of multiple sources can be separately estimated in each dimension regardless of coherence. Thus, a great amount of computational work required...

We describe an implementation of a polynomial system solver to compute the approximate solutions of a 0-dimensional polynomial system with finite precision p-adic arithmetic. We also describe an improvement to an algorithm of Caruso, Roe, and Vaccon for calculating the eigenvalues and eigenvectors of...
Therefore, to reduce the computational time, the inverse term is replaced with a summation term based on the eigenvalue and eigenvector in the inverse solver. In this paper, a fast inversion method using eigenvalue and eigenvector is developed to monitor the conductivity distribution. Therefore, ...
