You'll have to explicitly state in the derived class which type of the
base class you want to use, ie:

   template <class C>
      class Base<T> { };

   template <class C>
      class Derived<C> : Base <C> { };

or similar, or simpler, like fewer template dependencies.

By the way, for good programming practice, consider deriving Matrix from
Vector rather than the other way round...
