DMSNESSetJacobian#
set SNES Jacobian evaluation function
Synopsis#
#include "petscsnes.h"
#include "petscdm.h"
PetscErrorCode DMSNESSetJacobian(DM dm, PetscErrorCode (*J)(SNES, Vec, Mat, Mat, void *), void *ctx)
Not Collective
Input Parameters#
Note#
SNESSetJacobian() is normally used, but it calls this function internally because the user context is actually
associated with the DM.
Developer Note#
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.
