template functions in template class

Dear All,

I am confused about the template functions in template class. Such as I
have

template class A <class T, int n>

In side the class, I have

function A<T,nfun() and

template function void A<T,nfun <class T2, int n2>

So how to define them rightly?

template<class T, int n>
A<T, n A<T,n>::fun()
{...}

template<class T2, int n2>
template<class T, int n>
A<T, n A<T,n>::fun()
{...}

Are they right? For the first one as what I write, I think we can also
think it is a template function as A<T,nA<T,n>::fun<T,n>(), am I
right?

I appreciate you kind help!

Regards!

This is wrong.

The template function falls within the template class. Therefore the
template-id's for the class come first.

template<class T, int n>
template<class T2, int n2>
A<T, n A<T,n>::fun()
{...}
