Okay Jaroslav
add the comunicator, so I will learn about how to read mpi.h.

Sure no problem.
I used only MPI_COMM_WORLD because i simply wanted to make some tests and make
the things very easy.
I was thinking about a special octave_value_MPI that has a method
is_comunicator().
Deriving new octave_base_value subclasses in dynamically linked files is a
little tricky, so I'd recommend not doing it unless needed. Since the
communicator is always a fixed position argument, I think it doesn't need a
separate class, besides, it's usually just a handle.
MPI_Comm is usually an integer, so I think we can just provide a pair of
MPI_Comm -> octave_value and octave_value -> MPI_Comm converters and choose an
appropriate octave built-in type (int32, most likely).
I'll contribute this change if you agree.
I think also I have not implemented yet the recv octave_map and recv Cell,
because I was focusing only on ND array and sparse matrix. I tested it on the
past using pvm library. I will fix it with a test as soon as possible
Could you please tell me how you will update the files on svn by command line?
Thanks

If you have a checkout of the repository, doing
svn update
will fetch any changes from the central server to your disk. If there are
conflicts, you'll be asked to resolve them (merge).
To send a change to the server (commit), just edit some files and then do
svn commit -m "commit message"
If you're just starting with svn , I recommend you glance at a tutorial. The
official manual is at
http://svnbook.red-bean.com/
but probably any tutorial you can google out will do.
