Is there a method to compare vectors?
I have a plane, there are borders in this plane. And I need to know where is a point of the plane inside this border.

What is the best way to do this with Eigen?

(point.array()<topright.array()).all() && (point.array()>bottomleft.array()).all()

another option is to use our multi-dim aligned box:

if(AlignedBox<float,2>(bl,tr).contains(point)) ...
