SNESGetPicard
Returns the context for the Picard iteration
Synopsis
#include "petscsnes.h"
PetscErrorCode SNESGetPicard(SNES snes,Vec *r,PetscErrorCode (**f)(SNES,Vec,Vec,void*),Mat *Amat, Mat *Pmat, PetscErrorCode (**J)(SNES,Vec,Mat,Mat,void*),void **ctx)
Not Collective, but Vec is parallel if SNES is parallel. Collective if Vec is requested, but has not been created yet.
