Manipulation and Visualization of Sparse Matrices

ORSA Journal on Computing, 1990
An open architecture software environment for handling sparse matrices and interchanging sparse matrix data is proposed. The proposed educational and research environment includes tools for the visualization of sparse matrices. A prototype implementation of these ideas called the Sparse Matrix Manipulation System is described.

Parallel Inversion of Sparse Matrices.

IEEE Transactions on Power Systems, 1986
This paper presents a parallel algorithm for obtaining the inverse of a large, nonsingular symmetric matrix A of dimension nxn. The inversion method proposed is based on the triangular factors of A. The task of obtaining the "sparse inverse' of A is represented by a directed acyclic graph.

The structure of sparse resultant matrices

open access: yesProceedings of the 1997 international symposium on Symbolic and algebraic computation - ISSAC '97, 1997
Resultants characterize the existence of roots of systems of multivariate nonlinear polynomial equations, while their matrices reduce the computation of all common zeros to a problem in linear algebra.

Deterministic construction of sparse binary matrices via incremental integer optimization

open access: yesInformation Sciences, 2018
A central problem in compressed sensing (CS) is the design of measurement matrices. Compared with the conventional random matrices, sparse binary matrices have some attractive properties, such as lower storage/encoding cost and easy hardware ...

A Note on Fill for Sparse Matrices

SIAM Journal on Numerical Analysis, 1975
Suppose the sparse matrix A has a triangular factorization $LU$, where L is lower triangular and U is upper triangular. With the usual assumption that exact numerical cancellation does not occur during the factorization, $L + U$ is generally fuller than A. It is well known that this fill is confined to the envelope of A; that is, to positions which are

Learning the Domain of Sparse Matrices

2016 15th IEEE International Conference on Machine Learning and Applications (ICMLA), 2016
Large sparse linear system of equations arise in many areas of science and engineering. Although, there are several black-box general sparse solvers, usually they are not as effective as domain specific solvers. In addition, most solvers contain multiple choices during the solution process which can be tailored to a specific domain.
