Beyond AMLS: Domain decomposition with rational filtering
Vassilis Kalantzis, Yuanzhe Xi, Yousef Saad
This paper proposes a rational filtering domain decomposition technique for the solution of large and sparse symmetric generalized eigenvalue problems. The proposed technique is pu…
Sampling and multilevel coarsening algorithms for fast matrix approximations
Shashanka Ubaru, Yousef Saad
This paper addresses matrix approximation problems for matrices that are large, sparse and/or that are representations of large graphs. To tackle these problems, we consider algori…
Fast computation of spectral densities for generalized eigenvalue problems
Yuanzhe Xi, Ruipeng Li, Yousef Saad
The distribution of the eigenvalues of a Hermitian matrix (or of a Hermitian matrix pencil) reveals important features of the underlying problem, whether a Hamiltonian system in ph…
SMASH: Structured matrix approximation by separation and hierarchy
Difeng Cai, Edmond Chow, Yousef Saad +1
This paper presents an efficient method to perform Structured Matrix Approximation by Separation and Hierarchy (SMASH), when the original dense matrix is associated with a kernel f…
