Creates an empty vector object. The type can then be set with <A HREF="../Vec/VecSetType.html#VecSetType">VecSetType</A>(), or <A HREF="../Vec/VecSetFromOptions.html#VecSetFromOptions">VecSetFromOptions</A>().

PetscErrorCode VecCreate(MPI_Comm comm, Vec *vec)
</PRE>
If you never call <A HREF="../Vec/VecSetType.html#VecSetType">VecSetType</A>() or <A HREF="../Vec/VecSetFromOptions.html#VecSetFromOptions">VecSetFromOptions</A>() it will generate an
error when you try to use the vector.
