PetscMapInitialize

given a map where you have set either the global or local size sets up the map so that it may be used.

Synopsis

#include "petscvec.h"   
#undef __FUNCT__  
#define __FUNCT__ "PetscMapInitialize"
PetscErrorCode PETSCVEC_DLLEXPORT PetscMapInitialize(MPI_Comm comm,PetscMap *map)
Collective on MPI_Comm

Input Parameters

comm - the MPI communicator
map - pointer to the map

Notes

You must call PetscMapSetBlockSize() and either PetscMapSetSize() or PetscMapSetLocalSize() before calling this routine.

Unlike regular PETSc objects you work with a pointer to the object instead of the object directly.
