movie of particle tracking in MATLAB

I am writing a basic code to trace a streamline in MATLAB. I need to make a movie of the particles tracing a streamline (streakline). I know about streamparticles function but that isn't what I am looking for, I wish to select a particular streamline and trace a particle on that and record that motion. Is there some other method to accomplish this?

Here is the modified example from MATLAB help. Extract data from streamline and make animation
clc,clear
[x,y] = meshgrid(0:0.1:1,0:0.1:1);
u = x;
v = -y;
quiver(x,y,u,v)
startx = 0.1:0.1:1;
starty = ones(size(startx));
h1 = streamline(x,y,u,v,startx,starty);
xx = get(h1(2),'xdata'); % extract data for line2
yy = get(h1(2),'ydata');
h = line(xx(1),yy(1),'marker','o','markersize',15); % draw marker at start position
for i = 1:length(xx)
set(h,'xdata',xx(i),'ydata',yy(i)) % change marker position
pause(0.05)
end

If you want a movie, like an mp4 or avi video file, see my attached demo.
