MatColoringSetDistance#
Sets the distance of the coloring
Synopsis#
#include "petscmat.h"
PetscErrorCode MatColoringSetDistance(MatColoring mc, PetscInt dist)
Logically Collective
Input Parameters#
mc - the
MatColoringcontextdist - the distance the coloring should compute
Options Database Key#
-mat_coloring_type - the type of coloring algorithm used. See
MatColoringType.
Note#
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.
