Algèbre Linéaire - Linear Algebra

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.

The Matrix Market is a service of the Mathematical and Computational Sciences Division of the Information Technology Laboratory of the National Institute of Standards and Technology.

is a set of routines written in the ANSI C programming language and organized in the form of a library. This package is intended for solving large scale linear programming problems by means of the revised simplex method.

Software The Matrix Computation Toolbox (MATLAB).

Give your matrix (enter line by line, separating elements by commas).

Demonstrates 2-d transformations using a matrix.

LAPACK is written in Fortran77 and provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems. The associated matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are also provided, as are related computations such as reordering of the Schur factorizations and estimating condition numbers. Dense and banded matrices are handled, but not general sparse matrices. In all areas, similar functionality is provided for real and complex matrices, in both single and double precision.

Each generator is assembled into an application using intercommunicating Frames, Java and Javascript.

Most of the generators presented here are adapted from Nicholas J. Higham's worthwhile Test Matrix Toolbox.
