My mistake, I should be clearer. Something like 

boost::numeric::ublas::vector<double> aVector(4);

I guess the question is whether I can get at the raw data in 'aVector'
and pass it out as though it was a standard Corba type such as

double aCorbaVector[4]

I am trying to avoid an assignment step like:

for(i=0;i<4;i++) aCorbaVector[i]=aVector[i];

In my fantasy world, I'd hoped I might be able to do something like:

aCorbaVector = aVector.data();

where data() returns a pointer to the raw memory area.
