MatColoringSetMaxColors

Sets the maximum number of colors

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.
