Hi , I amd new using matlab and I would want to know how can I plot every generation of child ( xh) and see how has improve each generation in each iteration of jj. Total of generations are 200.

Code is below.

clear all
close all
clc
f = @(x,y) x*exp(-x^2 -y^2);
Ge = 200; %generations
N = 50;
D = 2;
xl = [-2 ; -2];
xu = [2 ; 2];
aptitud = zeros(1,N);
x = zeros(2,N);  %parents
for i=1:N
    x(:,i) = xl+(xu - xl).*rand(2,1);
end
 for jj=1:Ge
    for i=1:N
       fx = f(x(1,i),x(2,i));
       if fx >= 0
           aptitud(i) = 1/(1+fx);
       else
           aptitud(i) = 1+abs(fx);
       end
    end
    xh = zeros(2,N); % children
    for k=1:2:N
        
            p1 = seleccion(aptitud);
            p2 = p1;
            while p2 == p1
               p2 = seleccion(aptitud); 
            end
        [h1,h2] = cruza(x(:,p1),x(:,p2));
        xh(:,k) = h1;
        xh(:,k+1) = h2;
    end
    % disp(xh);
    
        pm = 0.3;
         for i=1:N
             for j=1:D
                if rand > pm 
                else
                    xh(j,i) = xl(j) + (xu(j) - xl(j))*rand();
                end
             end
         end
         x = xh;
    
 end
