Synopsis#

#include <petscts.h>  
PetscErrorCode TSComputeSNESJacobian(TS ts, Vec x, Mat J, Mat Jpre)

Collective

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)

Note#

Uses finite differencing when TS Jacobian is not available.
