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
