WebMar 12, 2016 · $\begingroup$ For some matrices (e.g., the original google page rank method) you're only after the Perron-Frobenius eigenvector and ignore the rest completely, and the matrix is large enough that you can't easily (or at all) solve linear systems with it. In the page rank case the number of nonzero entries would be something like the number of …

Iterative Methods for Computing Eigenvalues and Eigenvectors

WebThe Power Method, when applied to a symmetric matrix to obtain its largest eigenvalue, is more e ective than for a general matrix: its rate of convergence j 2= 1j2, meaning that it generally converges twice as rapidly. Let Abe an n nsymmetric matrix. Even more rapid convergence can be obtained if we consider a variation of the Power Method.
