- How did you obtain this value?
You said that you have points (coordinates of nose and eyes). I created some simple picture in paint and use cursor to find coordinates of eyes and nose

- and it is referring to both side of eyes?
No, it's only one eye
- cheek = [eye(1) nose(2)] what is the meaning of this? what does it do?
It takes X coordinate of eye and Y coordinate of nose. Simply intersection of horizontal and vertical lines
