In matlab, how to make a avi that sequentially fills square.

To make a code like .gif(actually .avi) first, i make a code like this to divide room.

 close all;
 figure;hold on;

 plot([0,8],[0,0],'black');
 plot([0,8],[8,8],'black');
 plot([0,0],[0,8],'black');
 plot([8,8],[0,8],'black');
 plot([2,2],[0,8],'black');
 plot([4,4],[0,8],'black');
 plot([6,6],[0,8],'black');
 plot([3,3],[0,8],'red');
 plot([5,5],[0,8],'red');
 plot([0,8],[2,2],'black');
 plot([0,8],[4,4],'black');
 plot([0,8],[6,6],'black');
 plot([0,8],[3,3],'red');
 plot([0,8],[5,5],'red'); 

 axis equal; 
 xlim([-1,9])
 ylim([-1,9])
 set(gca,'xtick',[-1:1:9]) 
 set(gca,'ytick',[-1:1:9])
