Suppose I have a point at location (3,800) and for this point, I have to select the nearest point. I have 3 points say (2,790), (3,770) and (2.5,780). How to find which one out of these three points is nearest to the given point (3,800)?

So where are you stuck? Give us a hint of what you're thinking so far. Maybe calculate the distances & take the mimimum?
>> p=[3;800];
q = [2,790;3,770;2.5,780].';
d = sum((p*ones([1,size(q,2)])-q).^2,1);
[~,minI] = min(d)
minI =
