Divide image into equal parts grid and save each part

Hi,
I have a several images with different height and width and I want to divide them into 9 equal parts (3x3 grid) and save each part into a separate file.
Is there a simple way to do it ? Is there a function that automatically apply the grid and split the image?
Thanks a lot in advance.
PS In case I am not clear I am looking to write something similar to the TileMage Image Splitter software (<http://tilemage.50webs.com/>) without GUI.

You could use blockproc or a double for-loop with imwrite().

If you called blockproc as
blockproc(A,[3,3],fun)
then the blocks will be 3x3. I don't know what you mean by "recall each block".
I also don't think anyone understands why you are still determined to use blockproc when there is only 1 block in the image that you care about (see Sean's last comment).

I think it's a bad idea to split the image into separate files, though. Why wouldn't it be better to keep them all in one file?

So then extract it
Icareabout = I(40:60,40:60,:) %extract a piece in the middle
If this is what you want then you should specify this in the question.
