MatFDColoring#

Object for computing a sparse Jacobian via finite differences with coloring

Synopsis#

typedef struct _p_MatFDColoring *MatFDColoring;

Notes#

This object is creating utilizing a coloring provided by the MatColoring object or DMCreateColoring()

The SNES option -snes_fd_coloring will cause the Jacobian needed by SNES to be computed via a use of this object
