Can an image be persistent with imshow or figure (II) ?

[amartinez]

NOTE: Sorry, I've corrected the question (image instead of figure in the
example):

Hello.

How can I make an image be persistent every time I use imshow or figure? I
want to to image processing with Octave.

This is an example of what I want to do. Only one window
is wanted but I always obtain a new window every time i use figure.

for i=1:20,
  x = rand(40);
  image(x);     % don't create a new window please ...   :(
end


Thanks in advance
