Sparse matrix test problems
These matrices are stored either in the compressed column format
(Harwell-Boeing format, see I. Duff et al.: Sparse Matrix Test Problems,
ACM Transactions on Mathematical Software, Vol. 15 No. 1,
March 1989, 1-14) or in the MatrixMarket coordinate format
(R.F. Boisvert et al.: The Matrix Market Exchange Formats: Initial Design,
NISTIR 5935, 1996).
Description of both formats can be found from
MatrixMarket.
- Cylindrical shell problems:
Short description (html), and slightly more informative
documentation (gzipped postcript-file cylshell.ps.gz, size 205 k).
