WebMoreover, the RRAT method is attractive for problems for which matrix-vector products with A are easier to evaluate than matrix-vector products with AT. This situation arises, e.g., when solving large nonlinear problems by Krylov subspace methods; see [11] for a discussion. It also arises when matrix-vector products are evaluated by multi-pole ...
