Group Bai

Group Description 
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.
