DMSNESComputeJacobianAction#
Compute the action of the Jacobian J(X) on Y
Synopsis#
#include "petscdmplex.h"
#include "petscsnes.h"
PetscErrorCode DMSNESComputeJacobianAction(DM dm, Vec X, Vec Y, Vec F, void *user)
Input Parameters#
dm - The
DMX - Local solution vector
Y - Local input vector
user - The user context
Output Parameter#
F - local output vector
Note#
Users will typically use DMSNESCreateJacobianMF() followed by MatMult() instead of calling this routine directly.
This only works with DMPLEX
Developer Note#
This should be called DMPlexSNESComputeJacobianAction()
