@us
Your point about the missing file is well taken. However I dont think it would have been optimal to bundle the dataset with each submission. While one can argue whether file exchange is the best repository for this code, I dont think comparing the contest entries to regular file exchange submissions is valid. Moreover I feel that there is definitely something to gain from examining the entries in this contest. I certainly have.

@Doug
Thats a nice idea. In the spirit of over-engineering things, I extended your idea further to actually do the download and extract the dataset.

% GET_CONTEST_DATA Download dataset for the Data visualization contest 2009
% GET_CONTEST_DATA(WD) Downloads the data to the folder WD
function get_contest_data(cwd)
url='http://www.mathworks.com/matlabcentral/fileexchange/23509?controller=file_infos&download=true';
if (exist (cwd, 'dir'))
try
    td=tempname;
    outfile = fullfile(td,'entry1.zip');
    datafile = fullfile(td,'contest_data.mat');
    mkdir (td);
    urlwrite(url,outfile);
    unzip (outfile, td);
    movefile(datafile, cwd);
    rmdir(td,'s');
catch
    err=lasterror;
    disp(err.message)
end
else
     error('Folder %s not found', cwd)
end

09 Apr 2009 Finding the Similar Entries: A Quantitative Approach based on CPU Runtime Behavior Entry to Matlab contest Spring 2009 Author: C Jethro Lam

Really like this approach to comparing code.

Very cool entry! Well commented code and lots of neat GUI techniques.

07 Feb 2012 Rasterplot Plotting Routine to display neural spike trains Author: Rajiv Narayan Buiatti, Marco

I agree very useful thanks.

13 Jan 2012 Ellipseselect An interactive ellipse selection tool Author: Rajiv Narayan Pepperl, Anathea

This code was very helpful and easy to use.

Btw, I think we both wrote some fancy scripts to generate the country flag of Finland. :)

Small suggestion: you may flip the x-axis, so that readers won't need to travel twice the board size to read the correlation of the entry located at the end.

wow, I learnt a lot from you guys...

The rules said "The thing you will be judging is the HTML document resulting from the published M-file"... so the main objective of a publish m file is still to generate the cleanest looking HTML. So adding these codes may not help the case... well, at least this is the direction I was heading towards. :)
