The original Harwell-Boeing collection. Iain Duff, Roger Grimes, and John Lewis.

See Other/userguide.ps.gz for details (also contains the specification of the
Harwell/Boeing format).

Each file in the true collection (see below) has already been split apart,
here.

Rank deficient matrices (a partial list):

	matrix	rank
	------	----
	saylr3	998
	zenios	265
	mbeause	447
	mbeacxc	448
	mbeaflw	448




The orginal Harwell/Boeing README file:

****************************************
The collection of sparse matrices from the Harwell-Boeing Collection (original 
release) are available by anonymous ftp from CERFACS.  They are in UNIX
compressed form, one file to each set in the collection.  The sets 
correspond to those identified in the Users' Guide (in file userguide.ps.Z)
Thus the BCSPWR set is designated as file bcspwr.data.Z.
  
To access them you should ftp to orion.cerfacs.fr (138.63.200.33) and
change directory to pub/harwell_boeing.

Then after changing mode to binary (bin) you can "get" the files you want.
  
The README file in pub/harwell_boeing follows this message.
