Webb12 dec. 2024 · Iterations oscillate between these two vectors, thus the iterations do not converge. The convergence rate of power method is determined by the ratio ρ = λ 1 / λ 2 ≥ 1, where λ 1 and λ 2 are the first and second largest eigenvalues (in magnitude). The larger the ratio is, the better convergece rate the iteration have. WebbApply the power method to A with initial vector v and print successive values of lambda. Do the scalars lambda converge quickly or slowly to the largest eigenvalue of A? Hint: Compute all eigenvalues of A with the MATLAB function eig. Exercise 5.
