University of Florida Sparse Matrix Collection:
Sources of some matrices and related links
Many of the matrices in the collection come from original
sources - computational scientists with a sparse matrix problem to solve.
Others come from researchers like myself, who work on algorithms for
sparse matrix and related graph problems. Researchers of both types
who maintain their own web pages or ftp sites for their matrices include:
- Harwell/Boeing Collection,
Iain Duff, Roger Grimes, John Lewis.
