A Robust Hierarchical Solver for Ill-conditioned Systems with Applications to Ice Sheet Modeling
Chao Chen, Leopold Cambier, Erik G. Boman +3
A hierarchical solver is proposed for solving sparse ill-conditioned linear systems in parallel. The solver is based on a modification of the LoRaSp method, but employs a deferred-…

Low-Rank Kernel Matrix Approximation Using Skeletonized Interpolation With Endo- or Exo-Vertices
Zixi Xu, Léopold Cambier, François-Henry Rouet +4
The efficient compression of kernel matrices, for instance the off-diagonal blocks of discretized integral equations, is a crucial step in many algorithms. In this paper, we study…
