DMTSSetIJacobian

set TS Jacobian evaluation function into a DMTS

Synopsis

#include "petscts.h" 
PetscErrorCode DMTSSetIJacobian(DM dm, TSIJacobianFn *func, void *ctx)

Not Collective

Input Parameters

• dm - DM to be used with TS

• func - Jacobian evaluation routine, see TSIJacobianFn for the calling sequence

• ctx - context for residual evaluation

Note

TSSetIJacobian() is normally used, but it calls this function internally because the user context is actually associated with the DM. This makes the interface consistent regardless of whether the user interacts with a DM or not. If DM took a more central role at some later date, this could become the primary method of setting the Jacobian.
