The matlab function 'mean' rearranges the set of data so that the mean of the x and y axes is zero, and the adjusted points are named Rctr.Rctr points that are more than 0.5 radius from the origin are removed, and the resulting set of points is named Rcirc, i.e. the points in Rcirc are in a circle of 0.5.
I want to make p2, p3 images So I maked this code for p1 clc;clear N=1000; A=rand(2,N); x=A(1,:); y=A(2,:); subplot(1,1,1); plot(x,y,'+'); hold on set(gca,'YTick',[0:0.1:1]);

N=1000;
A=rand(2,N);
x=A(1,:);
y=A(2,:);
x = x-mean(x);
y = y-mean(y);
idx = x.^2+y.^2<=0.25;
x=x(idx);
y=y(idx);
plot(x,y,'+')
