Nice trick. And thanks for the code. :)

I will probably play with a larger matrix to add some borders around the
images, but I get the idea.

Is it worth I describe my PostScript output issue, since I am using
octave2.0 ? Please have a look a this folder:
http://yo.dan.free.fr/test_octave/
 * test.ppm is the correct output
 * test.eps is messed up
 * test16.eps is obtained by saveimage("test16.eps", foo/16, ...)
   It's like tiled. A byte-order issue, somehow?

The script KL.m is also there, and enough data (train-images-..., the file
is truncated) as well.

I might use this solution instead if I am to add a label below each image.
Thanks for the idea (I didn't know this montage command).

Thanks all, and regards.
