How to eliminate some coordinates values?

I have coordinates (x,y) as point1 (2,4) point2 (4,6) point3 (6,20) point4 (20,26) point5 (15,6) i want to eliminate the x coordinates only, whose values are greater than or equal to 15 not for y coordinates. so, the answer is to be point1 (2,4) point2 (4,6) point3 (6,20)

points = [2,4; 4,6; 6,20; 20,26; 15,6];

out = points(points(:,1) < 15,:);
