Synopsis
#include "petscts.h"  
PetscErrorCode TSComputeSNESJacobian(TS ts,Vec x,Mat J,Mat Jpre)
Input Parameters
|  | ts | - the TS context obtained from TSCreate() | 
|  | x | - state vector | 
Output Parameters
|  | J | - Jacobian matrix | 
|  | Jpre | - preconditioning matrix for J (may be same as J) | 
Notes
Using SNES to compute the Jacobian enables finite differencing when TS Jacobian is not available.
