I want to extract the point (x,y) that is available near the center of the square. Also, I have all (x,y) coordinates of the points available in this plot.

I need a point that is nearer to the center of the square.

minx = min(x);
maxx = max(x);
centx = (minx + maxx) / 2;
miny = min(y);
maxy = max(y);
centy = (miny + maxy) / 2;
dist2 = (x - centx).^2 + (y - centy).^2;
[mindist2, idx] = min(dist2);
bestx = x(idx);
besty = y(idx);

x = rand(1,100);
y = rand(1,100);
plot(x, y, 'r*')
hold on
plot(mean(x), mean(y), 'k*', 'MarkerSize', 20)

I need a point that is nearer to the center of the point in the square. Not to plot an another point in the center.
