n=input('donner le nombre de points') k=0; for i=1:n u1=rand;u2=rand; x=2*u1; y=2*u2; if(y<=[(4*x)/(x^2 +1)]-[x*(x-12)]) k=k+1; end end Surface = k/n;

This works for me:

n=input('donner le nombre de points: ');
k=0; 
for i=1:n 
    u1=rand;u2=rand; 
    x=2*u1; 
    y=2*u2; 
    if(y<=[(4*x)/(x^2 +1)]-[x*(x-12)])
        k=k+1; 
    end
end
Surface = k/n;
disp(Surface)
