Connecting points of two scatterplots

I have two scatter plots and I want to connect the points from the one plot to the points of the other. I have this code:

scatter(cells(:,1),cells(:,2), 8, 'r', 'filled');
scatter(integrins(:,1),integrins(:,2), 8, 'g', 'filled');

I basically want to connect the red dot and the green dot.

I tried doing this,but there is a problem with the lengths of the vectors

   plot(cells, integrins, '-k')
   hold on
   scatter(cells(:,1),cells(:,2), 8, 'r', 'filled');
   scatter(integrins(:,1),integrins(:,2), 8, 'g', 'filled');
   hold off

Anyone know how to do this?

How does that code connect the red and green dots?

Also, if there is not a one-to-one correspondence between the red and green coordinates, how should they be connected?

DEMO

Create data

x1 = sort(rand(1,10)*10); 
x2 = sort(rand(1,10)*10); 
y1 = rand(1,10)*2;
y2 = rand(1,10)*4; 

Create scatter plot

figure
hold on
scatter(x1,y1, 30, 'r', 'filled');
scatter(x2,y2, 30, 'g', 'filled');

Add connector lines

• The notation (:)' merely forces each array to become a row vector.
• plot(x,y) creates a lines for each column of x and y.
• x1,x2,y1,y2 must all have the same number of elements.

plot([x1(:)';x2(:)'], [y1(:)';y2(:)'], 'k-')

Did you try quiver()?
