Recursively Preconditioned Hierarchical Interpolative Factorization for Elliptic Partial Differential Equations
Jordi Feliu-Fabà, Kenneth L. Ho, Lexing Ying
The hierarchical interpolative factorization for elliptic partial differential equations is a fast algorithm for approximate sparse matrix inversion in linear or quasilinear time.…
