Synopsis
#include "petscmat.h"
PetscErrorCode MatColoringSetMaxColors(MatColoring mc,PetscInt maxcolors)
Logically Collective on MatColoring
Input Parameter
| mc | - the MatColoring context
|
| maxcolors | - the maximum number of colors to produce

Notes
This may be used to compute a certain number of
independent sets from the graph. For instance, while using
MATCOLORINGMIS and maxcolors = 1, one gets out an MIS. Vertices
not in a color are set to have color maxcolors+1, which is not
a valid color as they may be adjacent.
