Create graph in 3 dimension

I have create an iteration as following:

format long

A=[1 0 2; -1 3 4; 2 1 0]

x_n=[-2 4 -3]'

for n=1:50

      b_n(:,n)=A*x_n(:,n);

      prox1(:,n)=1/3*((b_n(:,n))+[8 10 -8]');

      y_n(:,n)=b_n(:,n)-prox1(:,n);

      z_n(:,n)=A'*y_n(:,n);

      h(n)=1/2*(norm(y_n(:,n)))^2;

      gradh(n)=(norm(z_n(:,n)))^2;

      u(n)=2*h(n)/gradh(n);

      r_n(:,n)=x_n(:,n)-u(n)*z_n(:,n);

      prox2(:,n)=1/3*(r_n(:,n)+[-2 -4 5]');

      x_n(:,n+1)=((1/(1000*(n+1)))*[1 1 1]')+((1-(1/(1000*(n+1))))*prox2(:,n))
  end

Now, I would like to plot all the values as points in the same three dimensional coordinate. If possible, how should I do?

Thank you so much in advance.

Please be specific about which values are to be which axis. Are you looking for a series of 3D lines, x_n(:,n) vs y_n(:,n) vs z_n(:,n) ?

plot3(x_n, y_n, z_n)

possibly, depending on what you want plotted.
