Compute the SNESJacobian

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.
