SNESTSFormJacobian

 Function to evaluate the Jacobian

Synopsis

#include "petscts.h"  
PetscErrorCode  SNESTSFormJacobian(SNES snes,Vec U,Mat A,Mat B,void *ctx)
Collective on SNES

Input Parameter

snes - nonlinear solver
U - the current state at which to evaluate the residual
ctx - user context, must be a TS

Output Parameter

A - the Jacobian
B - the preconditioning matrix (may be the same as A)
flag - indicates any structure change in the matrix

Notes

This function is not normally called by users and is automatically registered with the SNES used by TS.
