Fast multipole method fmm
WebThe fast multipole method (FMM) was originally introduced by Greengard and Rokhlin and since their contribution, it has become clear that such matrices do arise commonly in practice. The work on... WebOct 15, 1994 · The fast multipole method (FMM) of Greengard evaluates Coulomb interactions of point charges with computational requirements that increase linearly with the number of particles. In this work, the central transformations of the FMM are obtained in a very compact manner from simple algebraic manipulations of two addition theorems.
