DMTSSetIJacobian
set TS Jacobian evaluation function
Synopsis
#include "petscts.h"
PetscErrorCode DMTSSetIJacobian(DM dm,TSIJacobian func,void *ctx)
Not Collective Many br
Input Argument
| dm | - DM to be used with TS Many br |
| func | - Jacobian evaluation function, see TSSetIJacobian() for calling sequence Many br |
| ctx | - context for residual evaluation Many br |
Many br
Note
TSSetJacobian() is normally used, but it calls this function internally because the user context is actually Many brassociated with the DM. This makes the interface consistent regardless of whether the user interacts with a DM or Many brnot. If DM took a more central role at some later date, this could become the primary method of setting the Jacobian. Many br
