I want to display the same image 16 times with 4 different rotations (0,90,180,270 degrees), each for 1 secs with a gap of 0.5 secs in between. How can I do it ?

I assume you are talking about 2D images:

% prepare an image but hide it initially (for better timing)
h = imagesc(peaks, 'Visible', 'off')
daspect([1,1,1])        % display image without distortion 
axis off                % don't draw axes
for alpha = 0:90:1350   % this produces a total of 16 images
    % display the image view for one second
    view(alpha,90)
    h.Visible = 'on'
    pause(1)
    % hide the image for half a second
    h.Visible = 'off'
    pause(0.5)
end
