# SNESGetPicard

Returns the context for the Picard iteration

### Synopsis

    #include "petscsnes.h"
    PetscErrorCode  SNESGetPicard(SNES snes,Vec *r,PetscErrorCode (**SNESFunction)(SNES,Vec,Vec,void*),Mat *Amat, Mat *Pmat, PetscErrorCode (**SNESJacobianFunction)(SNES,Vec,Mat*,Mat*,MatStructure*,void*),void **ctx)

Not Collective, but Vec is parallel if SNES is parallel. Collective if Vec is requested, but has not been created yet.
