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.
