  This directory contains sequential matrix coloring routines.
The routines were originally coded in Fortran 77 for the Minpack-1
project. They have been converted to C using the f2c package 
and then manually cleaned up so as not to require the f2c libraries
or include files.

   - August 1984. Thomas F. Coleman, Burton S. Garbow, Jorge J. More'
