Matrix Market test data

Nine sparse matrices that ArrayFire's sparse tests read, from the SuiteSparse Matrix Collection, formerly the University of Florida Sparse Matrix Collection.

License

The matrices are licensed under CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/) by the SuiteSparse Matrix Collection. The BSD license of this repository (LICENSE) does not apply to this folder.

The files are unchanged

Each file is the collection's Matrix Market file, byte for byte, with its metadata header (name, id, date, author, editor, kind) intact. Only each matrix's main <name>.mtx is included: the collection's archives also hold extra vectors for some matrices, which the tests don't use.

Citation

As the collection asks, please cite it when you use these matrices:

Each file is at matrixmarket/<group>/<name>/<name>.mtx, the layout ArrayFire's tests expect.
