#include "petscvec.h"  
PetscErrorCode  VecRegister(const char sname[], PetscErrorCode (*function)(Vec))
Not Collective

Input Parameters

name - The name of a new user-defined creation routine
create_func - The creation routine itself

Notes

VecRegister() may be called multiple times to add several user-defined vectors

Sample usage

    VecRegister("my_vec",MyVectorCreate);

Then, your vector type can be chosen with the procedural interface via

    VecCreate(MPI_Comm, Vec *);
    VecSetType(Vec,"my_vector_name");
or at runtime via the option
    -vec_type my_vector_name
