ISColoring

 sets of IS's that define a coloring of the underlying indices

Synopsis

struct _n_ISColoring {
  PetscInt        refct;
  PetscInt        n;                /* number of colors */
  IS              *is;              /* for each color indicates columns */
  MPI_Comm        comm;
  ISColoringValue *colors;          /* for each column indicates color */
  PetscInt        N;                /* number of columns */
  ISColoringType  ctype;
};

Notes

One should not access the *is records below directly because they may not yet have been created. One should use ISColoringGetIS() to make sure they are created when needed.

Developer Note: this is not a PetscObject
