Doxygen complains that vector<>.resize is not documented

Question

I'm trying to learn Doxygen.

I almost have all warnings and errors found. However there are two that I cannot figure out.

My code is something like

namespace SE{

//! Description etc
template <typename _T>
class MyClass{

public:
       MyClass(int, int);

private:
       std::vector<std::vector<_T>> data;
       double X;      //< Description
}

//! Description etc
template <typename T>
MyClass<T>::MyClass(int rows, int cols){
       data.resize(rows, std::vector<T>(cols));
}

} /* End of namespace SE*/

When I try to process it with doxygen I am getting a warning:

warning: Member resize(rows, std::vector< T >(cols)) (function) of namespace SE is not documented

It looks like it thinks that this is my own function. How do I tell Doxygen it is from std::vector?

I also have another member function defined outside of the function body which has a for loop and I am getting

warning: Member for(auto i=0;i< n;++i) (function) of namespace SE is not documented.

I also had another function where I had a member variable, X, and when I was writing the function outside the class definition body, it said that X was not documented.

//! Description etc.
void MyClass::myfunc(){
      X=2.0;       // Doxygen complained here
}

I was able to "fix" it by doing

void MyClass::myfunc(){
      MyClass::X=2.0;       // Doxygen warning suppressed
}

or

void MyClass::myfunc(){
      this->X=2.0;       //  Doxygen warning suppressed
}

Should I have needed to do this?

EDIT: I also have the issue that in the documentation I have:

 Functions
        SE::for (auto i=0;i< n;++i)

data    SE::resize (n, std::vector< T >(m))

in the generated documentation
