A simple numerical experiment of Green's function expansion in the Fast Multipole Method
Advanced Electromagnetics, 2017 In this paper the theoretical foundation of the fast multipole method applied to problems involving electromagnetic scattering is briefly presented, the truncation of the Green’s function expansion is revisited, and the well established truncation ...

The Inverse Fast Multipole Method
CoRR, 2014 This article introduces a new fast direct solver for linear systems arising out of wide range of applications, integral equations, multivariate statistics, radial basis interpolation, etc., to name a few. \emph{The highlight of this new fast direct solver is that the solver scales linearly in the number of unknowns in all dimensions.} The solver ...

Fast multipole methods for particle dynamics [PDF]
Molecular Simulation, 2006 The growth of simulations of particle systems has been aided by advances in computer speed and algorithms. The adoption of O(N) algorithms to solve N-body simulation problems has been less rapid due to the fact that such scaling was only competitive for relatively large N.

A fast direct solver for surface-based whole-head modeling of transcranial magnetic stimulation
Scientific Reports, 2023 When modeling transcranial magnetic stimulation (TMS) in the brain, a fast and accurate electric field solver can support interactive neuronavigation tasks as well as comprehensive biophysical modeling. We formulate, test, and disseminate a direct (i.e.,
