You need to put the complete code for:

template<int size, typename Base>     void   func( Vector<size,double,Base> > 
a);

into the header file. Then the compiler can generate the code you need and 
you won't get link errors. As an added bonus, the compiler sill also be 
able to do a better job of optimization.
