In this article, we describe the integration of a multiresolution (MR) approach into a few fast factorization methods for the method‐of‐moments (MoM), with specific attention to the analysis of large nonperiodic arrays. The MR approach allows a physics‐based preconditioning scheme (as opposed to algebraic preconditioners) that requires a low‐memory occupation and a low‐computational cost for its generation and application to fast factorizations. In particular, we present a theoretical and experimental analysis that shows that the complexity of the resulting fast‐MR algorithm is still of the order of the original fast factorization method. © 2010 Wiley Periodicals, Inc.
