Function specialization for arrays not being called

Question

I have a function which is templated on its argument:

template <class Vector>
void F(Vector& vec);

I want to add a specialization of this function for numeric arrays. My attempt looks like this:

template <class NumType>
void F(NumType array[]);

I am having difficulty in calling the specialized function in the code. See below:

void main()
{
  double a[] = {0.0, 1.0};
  F(a); // This calls the Vector version of the function,
        // with Vector = double [3], in my specific case.
}

If it helps, I do know beforehand that the function needs a length 3 array to work properly.

How do I fix my specialized function declaration so the NumType array version of the function is called?

Thanks

Try

template <class NumType, size_t N>
void F(NumType (&array)[N]);
