[ublas] How to zero-initialize a vector?

Hello.

I see that there is some discussion about the initialization to zero of 
vector elements and I understand that the default behaviour is to left 
them uninitialized (even if the documentation claims that 'Elements are 
zeroed by default' in the overview).

Is there a way to change this behaviour with a macro, a template 
parameter or something else?

I simply want to have this:

   typedef boost::numeric::ublas::??? my_vector_type;
   my_vector_type my_vector(1);
   assert (my_vector[0]==0.0);

Thank you.
Marc.
