# 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
