DMTSGetIJacobian#
get TS Jacobian evaluation function
Synopsis#
#include "petscts.h"
PetscErrorCode DMTSGetIJacobian(DM dm, TSIJacobian *func, void **ctx)
Not Collective
Input Parameter#
dm - DM to be used with TS
Output Parameters#
func - Jacobian evaluation function, see TSSetIJacobian() for calling sequence
ctx - context for residual evaluation
Note#
TSGetJacobian() 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.
