Dear All,
        I'm not a Octave user but I've just installed it in a Docker container and I'm looking for stunning demos to demonstrate how it works (e.g.. really cool plot).

I've found "Visualizing the Lorenz Strange Attractor with Octave" on
http://www.ibm.com/developerworks/library/l-datavistools/  (Listing 4), but it is done with Octave 2.1.50 and I'm running the last one (3.8.1 in a ubuntu-like docker). Get some error when running it.
Can someone would be kind enough to help me to plot the same graph on the latest version or head me to some other "up to date" cool plot scripts ?

In case of someone is interessted in the docker file / image, you can check it out on https://registry.hub.docker.com/u/epflsti/octave-x11-novnc-docker/

Thanks in advance,
Nicolas

try this

1

 function y = lorenz( x, t )

y = [10 * (x(2) - x(1));

x(1) * (28 - x(3));

x(1) * x(2) - 8/3 * x(3)];

endfunction

 x = lsode("lorenz", [3;15;1], (0:0.01:25)');

 

 plot3(x(:,1),x(:,2),x(:,3))
