@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.

17 May 2013 Psth Computes the peri-stimulus time histogram for neural spike times Author: Rajiv Narayan Franziska

Hello Mr. Narayan

This function is very nice and helpful and working perfectly. Still I have one question. So far i didn't manage to insert it in a subplot. The picture is always appearing as an independent figure. Could you please help me with creation of a subplot?
Thank you

18 Jan 2013 Ellipseselect An interactive ellipse selection tool Author: Rajiv Narayan Mech Princess

The coolest & useful program ever. To edit the ellipse in real time, you should unselect the arrow on top (took a while to figure it out)

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

I agree very useful thanks.

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

This code was very helpful and easy to use.

10 Apr 2009 Code overlap The aim here is to visualize the degree of overlap between all pairs of entries in the contest. Author: Rajiv Narayan C Jethro Lam

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.
