This directory contains the Harwell Y12M sparse LU decompositon routines,
as obtained from netlib (url given in ./www) in September 2002.

Y12MAE		single precision driver
Y12MAF		double precision driver

Y12MF		iterative improvement

Y12MB[EF]	analyse
Y12MC[EF]	factor (LU decompose)
Y12MD[EF]	solve given LU decomposition
