A Fast Solver for HSS Representations via Sparse Matrices
In this paper we present a fast direct solver for certain classes of dense structured linear systems that works by first converting the given dense system to a larger system of block sparse equations and then uses standard sparse direct solvers. The kind of matrix structures that we consider are induced by numerical low rank in the off-diagonal blocks of the matrix and are related to the struct...
متن کاملsymPACK: a solver for sparse Symmetric Matrices
Systems of linear equations arise at the heart of many scientific and engineering applications. Many of these linear systems are sparse; i.e., most of the elements in the coefficient matrix are zero. Direct methods based on matrix factorizations are sometimes needed to ensure accurate solutions. For example, accurate solution of sparse linear systems is needed in shift-invert Lanczos to compute...
متن کاملA Fast and Memory Efficient Sparse Solver with Applications to Finite-Element Matrices
In this article we introduce a fast iterative solver for sparse matrices arising from the finite element discretization of elliptic PDEs. The solver uses a fast direct multi-frontal solver as a preconditioner to a simple fixed point iterative scheme. This approach combines the advantages of direct and iterative schemes to arrive at a fast, robust and accurate solver. We will show that this solv...
متن کاملAn adaptive fast solver for a general class of positive definite matrices via energy decomposition
In this paper, we propose an adaptive fast solver for a general class of symmetric positive definite (SPD) matrices which include the well-known graph Laplacian. We achieve this by developing an adaptive operator compression scheme and a multiresolution matrix factorization algorithm which achieve nearly optimal performance on both complexity and well-posedness. To develop our adaptive operator...
متن کاملFast hierarchical solvers for sparse matrices
Sparse linear systems are ubiquitous in various scientific computing applications. Inversion of sparse matrices with standard direct solve schemes are prohibitive for large systems due to their quadratic/cubic complexity. Iterative solvers, on the other hand, demonstrate better scalability. However, they suffer from poor convergence rates when used without a preconditioner. There are many preco...
