We show in this paper how the convergence of an algorithm for matrix completion can be significantly improved by applying Wynn’s ε-algorithm. Straightforward generalization of the scalar ε-algorithm to matrices fails. However, accelerating the convergence of only the missing matrix elements turns out to be very successful.

Based on Neumman series and epsilon-algorithm, an efficient computation for dynamic responses of systems with arbitrary time-varying characteristics is investigated. Avoiding the calculation for the inverses of the equivalent stiffness matrices in each time step, the computation effort of the proposed method is reduced compared with the full analys...
