Abstract
In this paper, we present a post- compression method based on the Singular Value Decomposition that can be used to retrieve the low- rank representation of the Method of Moments in- teraction matrix after using the shielded-block pre- conditioner. Compression ratios of more than 17 has be achieved without significant loss of accuracy and can be further increased at the expense of the precision. The time needed to compress the pre- conditioned matrix is negligible with respect to the preconditioning time.
