Matrix Market: a web resource for test matrix collections
Ronald F. Boisvert, Roldan Pozo, Karin Remington, Richard Frederick Barrett, Jack J. Dongarra · 1996
We describe a repository of data for the testing of numerical algorithms and mathematical software for matrix computations. The repository is designed to accommodate both dense and sparse matrices, as well as software to generate matrices. It has been seeded with the well-known Harwell-Boeing sparse matrix collection. The raw data files have been augmented with an integrated World Wide Web interface which describes the matrices in the collection quantitatively and visually. For example, each matrix has a Web page which details its attributes, graphically depicts its sparsity pattern, and provides access to the matrix itself in several formats. In addition, a search mechanism is included which allows retrieval of matrices based on a variety of attributes, such as type and size, as well as through free-text search in abstracts. The URL is http://math.nist.gov/MatrixMarket/. 1 INTRODUCTION A frequently applied method for the testing of numerical software is to exercise it on a battery of...
