Bonjour,
Je besoin de tracer une figure qui contient 20 points randomisées dans une area [-100 100]. Je veux obtenir cette figure 10^6 càd 10^6 figures, chacune contient 20 points. pourriez vous m'aider,j'essaye d’utiliser la syntaxe rand(n)
merci
set(gca,'xtick',-100:20:100);
set(gca,'ytick',-100:20:100);
axis([-100 100 -100 100]);

What does "I want to get this figure 10 ^ 6 càd 10 ^ 6 figures" mean? How many figures do you want to create with 20 points each in them? And don't say an array of a million by a million figures. You can't fit a billion figures on your screen.

How about this:
x = 200 * rand(1,20) - 100;
y = 200 * rand(1,20) - 100;
plot(x, y, 'b*');
grid on;
