TSComputeSNESJacobian#
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.
