A visual repository of test data for use in comparative studies of algorithms for numerical linear algebra, featuring nearly 500 sparse matrices from a variety of applications, as well as matrix generation tools and services.

We briefly describe the ASCII file formats for matrices redistributed by the Matrix Market : Matrix Market Exchange Formats Harwell-Boeing Exchange Format Coordinate Text File Format (to be phased out) Note that most of the data files we distribute are compressed using gzip, and some are multifile archives based on Unix tar. Refer to our compression document if you need help in decoding these file

Draft Proposal for Java BLAS Interface Roldan Pozo National Institute of Standards and Technology The Basic Linear Algebra Subprograms (BLAS) library provides computational kernels for several of the fundamental linear algebra operations, such as matrix-multiply, the solution of triangular systems, and simple vector operations. Java BLAS conventions Java memory model Subvectors and 0/1 indexing Co

Background JAMA is a basic linear algebra package for Java. It provides user-level classes for constructing and manipulating real, dense matrices. It is meant to provide sufficient functionality for routine problems, packaged in a way that is natural and understandable to non-experts. It is intended to serve as the standard matrix class for Java, and will be proposed as such to the Java Grande For

An interface for scientific computing in C++ Roldan Pozo Mathematical and Computational Sciences Division National Institute of Standards and Technology The Template Numerical Toolkit (TNT) is a collection of interfaces and reference implementations of numerical objects useful for scientific computing in C++. The toolkit defines interfaces for basic data structures, such as multidimensional arrays

The JavaNumerics page provides a focal point for information on numerical computing in Java. This is an activity of the Java Grande Forum Numerics Working Group, chaired by Ron Boisvert and Roldan Pozo. Note. Some of the links below will take you away from NIST webspace. We are providing these links because we think they will be of interest to you; however, the views expressed and the decisions re
