TM>So you think of vectors in the mathematical sens of the term.
No; the mathematical sense of the term would require a very difficult
class; as a vector is anything, related to a field [the field of
scalars], that has sum of vectors and multiplication by scalar,
satisfying what you expect them to satisfy.
Is it possible to create a template class requiring in the TYPE
class some operators?
Something like:
template  class Finite_Dimensional_Field {
public:
  Field v[dimension];
// here force Field to have operator+(Field &, Field &) and ...
// operator*(Field &, Field &) and some other math stuff
};
TM>Then the val_array  class  template (also in the Standard C++
TM>Library) might be what you are looking for.
M$C++ doesn't include val_array :-(
