MatColoringSetDistance
Sets the distance of the coloring
Synopsis
#include "petscmat.h"
PetscErrorCode MatColoringSetDistance(MatColoring mc,PetscInt dist)
Logically Collective on MatColoring
Input Parameter
| mc | - the MatColoring context
|
| dist | - the distance the coloring should compute
|
Notes
The distance of the coloring denotes the minimum number
of edges in the graph induced by the matrix any two vertices
of the same color are. Distance-1 colorings are the classical
coloring, where no two vertices of the same color are adjacent.
distance-2 colorings are useful for the computation of Jacobians.
Keywords
