2 Ball is moving
I want to add 3th moving ball (start position (0,1))
How to is it?
Following is My Code :(For operate, Copy & Paste)
x1_st=0;y1_st=0.5;
x2_st=0;y2_st=1.5;
%plot
h_fg=figure;
h_ax=axes(h_fg);
h_p1=plot(h_ax,x1_st,y1_st,'b.','MarkerSize',40); hold(h_ax,'on');
h_p2=plot(h_ax,x2_st,y2_st,'r.','MarkerSize',40); hold(h_ax,'on');
% change Properties
set(h_ax,'XLim',[-5 5]);
set(h_ax,'YLim',[0 5]);
h_ax.YLim=[0 2];
h_ax.XLim=[-5 5];
% for loop
dx=[1:0.1:5, -5:0.1:0];
for ii=1:length(dx)
x1_new=x1_st+dx(ii);
x2_new=x2_st-dx(ii);
set(h_p1,'XData',x1_new);
set(h_p2,'XData',x2_new);
pause(0.02);
end

If you replace numbered variables with arrays you can use simple loops with indexing. With your current setup you will have to copy and paste every line of code referring to a ball.
