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