Alright I am implementing a static member function for the first time
and it is not working :(. Are static member functions implemented in
the header?

Not sure what you mean by "are". Mine aren't _usually_. If they are,
they are declared 'inline' (or implicitly inline if defined inside the
class definition).

header:

static float[4][8] GetPivot(float matrix[4][8], int n);

You can't return an array.

cpp:

static float[4][8] Matrix4x4::GetPivot(float matrix[4][8], int n) {

Drop 'static' from here. And fix the return value type.

...
}

and the errors:
