How to keep equal distancing between markers while moving??

Hi, how can I keep equal distancing (angles) between markers while moving so that they move at he same speed (f=0.5)?

Thank you!

clear
clc
figure
n= 10;     % Number of points
f = 0.5 ; % frequency
r = 2 ;   % Ratio
theta= linspace(0,360,n+1);
pp = plot(NaN,NaN,'o') ; 
axis(1.1*[-r r -r r]) ;   
axis square       
tic 
while(toc < 10)
   t = toc ;
   pp.XData = [r*cosd(theta*f*t)] ;
   pp.YData = [r*sind(theta*f*t)] ;
   drawnow
end

Since you are in a periodic space, scaling the angle will not preserve the distance, you should use addition ( translate the angle)

pp.XData = [r*cosd(theta + f*t)] ;
pp.YData = [r*sind(theta + f*t)] ;

It will be too slow, but you can make it faster by scaling the the frequency 1*45 ( pi/4) or 90 ( pi/2). As you want
