Display image for 1 second?

Elle We — Tue, 29 Apr 2008 22:24:02 -0400

I need to write a function such that an image is displayed
for 1 second before showing another
I used tic toc

s = load('clown');
t = load('cape');
time = 0;
image(s.X);
tic;
while time < 1
time = toc;
end
image(t.X)
[x,y] = ginput;

and when I run run it, I never get the clown but it jumps
to the cape right away. I tried it with "while time < 15"
and it would wait 15 seconds before a picture of the cape
pops up--I never get the clown. Thanks in advance for the
help

Try this:

figure;
s = load('clown');
t = load('cape');
time = 0;
image(s.X);

%this makes matlab draw the clown
drawnow

tic;
while time < 1
time = toc;
end
image(t.X)
