SNESTSFormJacobian#
Function to evaluate the Jacobian
Synopsis#
#include "petscts.h"  
PetscErrorCode SNESTSFormJacobian(SNES snes, Vec U, Mat A, Mat B, void *ctx)
Collective
Input Parameters#
- snes - nonlinear solver 
- U - the current state at which to evaluate the residual 
- ctx - user context, must be a - TS
Output Parameters#
- A - the Jacobian 
- B - the preconditioning matrix (may be the same as A) 
Note#
This function is not normally called by users and is automatically registered with the SNES used by TS.
