Requirements

This demonstration should work if you are running X-windows on a unix machine which has gnuplot.
If you have got gnuplot on some other system, it may work.
If you have not got gnuplot, I recommend you take a PC and put linux on it.

To run the demonstration:

  1. get the demonstration files (449K) by clicking here http / ftp or by anonymous ftp to www.inference.phy.cam.ac.uk, cd pub/www/mackay/itprnn/code/adler, binary, get demo.tar.gz.
  2. unpack thus: 
           gunzip demo.tar
       tar xvf demo.tar
    This unpacks a load of files into a directory called adler. 
  3.        cd adler
  4. modify your X windows defaults so that the gnuplot colours and fonts come out right. 
           xrdb -load Xdefaults.gnu
       
  5.        gnuplot
  6. To run the demo: 
           load 'gnu'
    During this sequence, hit return when you are ready for the next picture.
