SNESSetUpMatrices#
ensures that matrices are available for SNES Newton-like methods, this is called by SNESSetUp_XXX()
Synopsis#
#include "petscsnes.h"
PetscErrorCode SNESSetUpMatrices(SNES snes)
Collective
Input Parameter#
snes -
SNESobject to configure
Note#
If the matrices do not yet exist it attempts to create them based on options previously set for the SNES such as -snes_mf
Developer Note#
The functionality of this routine overlaps in a confusing way with the functionality of SNESSetUpMatrixFree_Private() which is called by
SNESSetUp() but sometimes SNESSetUpMatrices() is called without SNESSetUp() being called. A refactorization to simplify the
logic that handles the matrix-free case is desirable.
