uses a gmres iterative solver with a restricted additive Schwarz method (rasm) as a preconditioner ... fast matrix-vector algorithm. Previous fast rbf methods — achieving at most O(NlogN) complexity — were ... polyharmonic basis functions. In contrast, the present method uses Gaussians with a small variance with ... This is a common choice in particle methods for fluid simulation, our main target application...
