Supposing that pDblY0 exists, with  the required size, and pDblYOut is a 
types::Double*, does the following do the trick:

             pDblYOut = new types::Double(pDblY0->getRows(), 1);
             pDblYOut->set(pdYData);
             pDblYOutList.push_back(pDblYOut->get());

Thanks for hints, comments..
