How can I move to the next trial without generating new window of figure?

I'm working on generating attention shift task. And I'm very beginner of MATLAB. When I run this code, it kept generating new figure window. However, I want to make it goes to the next trial without generating new window with the figure. Could someone tell me what did I wrong? Thanks a lot!
DATA = zeros(80,1); % pre-allocation of data matrix
ExoHorizentalV100 = 0;
jj = 1;
while ExoHorizentalV100 < 80
coin = rand;
if coin < 0.5 % cue and target presented in the right
fig = figure;
set(fig,'position',get(0,'ScreenSize'))
r1 = rectangle('position',[0,150,100,100],'EdgeColor','k','Linewidth',3);
xlim([0 400])
ylim([0 400])
hold on
plot(200,200,'+','MarkerSize',30,'LineWidth',3,'Color','k');
hold on
r2 = rectangle('position',[300,150,100,100],'EdgeColor','k','Linewidth',3);
axis square;
axis off;
pause(4)
t = text(180,270,'\rightarrow','FontSize',40,'LineWidth',3,'Color','k');
pause(0.1)
set(t,'Visible','off')
plot(350,200,'kp','MarkerSize',30,'MarkerFaceColor','k')
pause(0.3)
elseif coin > 0.5 % cue and target presented in the left
fig = figure;
set(fig,'position',get(0,'ScreenSize'))
r1 = rectangle('position',[0,150,100,100],'EdgeColor','k','Linewidth',3);
xlim([0 400])
ylim([0 400])
hold on
plot(200,200,'+','MarkerSize',30,'LineWidth',3,'Color','k');
hold on
r2 = rectangle('position',[300,150,100,100],'EdgeColor','k','Linewidth',3);
axis square;
axis off;
pause(4)
t = text(180,270,'\leftarrow','FontSize',40,'LineWidth',3,'Color','k');
pause(0.1)
set(t,'Visible','off')
plot(50,200,'kp','MarkerSize',30,'MarkerFaceColor','k')
pause(0.3)
end
tic; pause ; temp = toc;
response = get(fig,'CurrentCharacter');
ExoHorizentalV100 = ExoHorizentalV100 + 1;
DATA(jj,1) = temp;
jj = jj + 1;
end

Take
fig = figure;
set(fig,'position',get(0,'ScreenSize'))
out of the loop
