Matrices from Z. Bai, D. Day, J. Demmel, and J. Dongarra. located at ftp.ms.uky.edu : pub/misc/bai/Collection. Modifications: Header line (line 1) of AF23560 modified - 11 null characters removed. Names changed to reflect the naming conventions at this site (lower case, followed by a 3 character extension with the matrix type - .rua, .rsa, etc.). Jan, 2003: Matrices with unsorted columns were sorted (originals in Jumbled directory). Apr 2003: Matrices with "(5E16)" format changed to "(5E16.8)". Originals in 5e16 directory. -------------------------------------------------------------------------------- Original README file: -------------------------------------------------------------------------------- This directory contains the data files for the test matrices.
