graph of iterative sequence

how can i get the graph of this iterative sequence

t=@(n)(1/(n+2)^2);r=1/5;
g=@(x)((x-1)/(exp(x)));
tolerance=0.000001;
k=100;
x=zeros(1,k);
x(1)=0.3977;
for n=1:k
    x(n+1)=(1-(r)*g(x(n)))*(1-t(n))*x(n);
    if abs(x(n+1)-x(n))<tolerance
        fprintf('The sequence converges after %d iterations for tolerance = %f', n, tolerance)
        break;
    end
end
x=x(1:n+1); %discard the zeros
format long
disp(x)

Add the command

plot(1:n+1,x)

at the end of your code.

is it possible to dispaly more than one graph by changing x(1)?

[Torsten]

t=@(n)(1/(n+2)^2);r=1/5;
g=@(x)((x-1)/(exp(x)));
tolerance=0.000001;
k=100;
N=20;
hold on
for NN=1:N
    x(1)=rand;
    for n=1:k
        x(n+1)=(1-(r)*g(x(n)))*(1-t(n))*x(n);
        if abs(x(n+1)-x(n))<tolerance
            fprintf('The sequence converges after %d iterations for tolerance = %f', n, tolerance)
            break;
        end
    end
    plot(1:n+1,x)
end
hold off
