28 Apr 2010 MATLAB Contest - Sensor All the files needed to develop and score an entry for the MATLABĀ® Programming Contest. Author: The MATLAB Contest Team

Nope.. opens fine for me.

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

This is a VERY cool analysis and definitely the best entry so far in the spirit of the competition, in that it visualizes some new nuggets of information data mined out of the data set.

08 Apr 2009 Improvement Focus Animation This is for the Data Viz contest Author: Alan Chalker

This is a corrected version of the previous entry where I fixed the text describing the animation.

08 Apr 2009 Animation of Leading Entry over Time This shows various things about the leading entry over time. Author: Alan Chalker

Oops.. I forgot to change the text explaining the animation. Obviously it's NOT a scatter plot with colors showing time. They are just normal plots over time.

07 Apr 2009 LINEAGE v1.1 LINEAGE helps visualize the evolution of the code throughout the Peg Solitaire contest Author: Kenneth Eaton

This is a very interesting entry to the competition, since it's basically an interactive UI that is the cool thing, not necessarily the published m file.

One other minor note, your images appear to be manually created and placed by hard coding tags into the published m file. I think the spirit of the competition is that someone be able to take just the m files and publish them on their own computers and replicate the output, which can't be done with this entry (however with some MATLAB kungfu you could create the images on the fly from with published m file)

04 Nov 2011 MATLAB Contest - Vines (Improved visualization tools) This is a modified version of the visualizevines.m and runcontest.m files that better shows the data Author: Alan Chalker Simon, Jan

I suggest to insert any useful information in the description. Currently this is confusing only.

To answer the question of using data not normally on the MATLAB path, I offer the following modification.

if ~exist('contest_data.mat','file')
warning ('This was an entry to the MATLAB programming contest (http://www.mathworks.com/contest/datavis/home.html). Please load the contest data and unzip it to place contest_data.mat on your MATLAB path.')
web('http://www.mathworks.com/matlabcentral/fileexchange/23509?controller=file_infos&download=true')
end

no H1 line, no help section, no example(s), loads a file, which the typical ML user does not have and, therefore, causes an error right away...
no appreciable benefit to any ML user...
