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.
