The power method algorithm
Webb7 jan. 2013 · I need to write a program which computes the largest and the smallest (in terms of absolute value) eigenvalues using both power iteration and inverse iteration. I can find them using the inverse iteration, and I can also find the largest one using the power method. But I have no idea how to find the smallest one using the power method.

WebbThe 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. Webb1 jan. 2024 · It indicates that the Arnoldi-PET algorithm can find out a compromise between the PET method and the Power–Arnoldi algorithm. That is, for the large matrix and α, relative to the PET method, the iteration counts have been reduced dramatically. At the same time, relative to the Power–Arnoldi algorithm, the computing time has been …
