Plotting continuous motion using loops

Hello, so I have code up and running that animates a few graphical objects for a theta = -65 : 0. I now want to do this same thing but keep the animation running back and forth between 0 and -65 and back again. Is there a way to do this with loops?

Currently my set up is similar to:

theta = linspace(-65,0);
i = length(theta);
while(i>0)
    y=sind(theta);
    y_plot = y*sind(theta(i));
    plot(theta,y_plot)
    i = i-1; 
    pause(0.1);
end

Try something along these lines:

% CREATE ANGLE ARRAY
theta = linspace(-65,0);
i = length(theta);

% LOOP FORWARD THEN BACKWARD
for n = [ 1:i i-1:-1:2 ]
    % Plot Stuff Here
end

If you're trying to create a loopable animation, this is the code to do it without duplicate frames that will look choppy. This way, it will be a smooth transition from forward to backward animation.

Let me know if you have questions or need any more help!
