MATLAB Programming Contest Blog

April 3rd, 2009

We will award an Early Bird prize for the entry with the most votes on Monday at noon EDT. For this mid-contest prize, there well be no designated voting period, so entries submitted earlier will have the opportunity to attract more votes.

As explained in the rules, you vote for an entry by tagging it “vis2009″. If you change your mind, simply remove your tag. All entries are listed on the Rankings page. Vote for as many entries as you’d like.

   Two questions / concerns I have:

   1. I just submitted an entry, and was surprised to NOT see it immediately appear online. Instead I got a message saying it needed to be reviewed and would take up to 5 days to appear?!?!?! I don’t even have any type of link or reference to the upload listed in my profile, so for all I know it will disappear into the ether. Who is doing the reviewing? Obviously this could significantly impact the ability of entries to get seen by others if they aren’t made public in a short amount of time.

   2. My entry happens to include a video (shameless plug.. go see it please.. it’s cool;). I figured out a way to make MATLAB create an AVI file and then display it as part of the published HTML. For this first submission, I deliberately kept the animation small and short, but the zip file is still over 2.5MB and uncompresses to over 150MB. Do we really need to include ‘all the published’ files? Downloading the .m file and running / publishing it produces the same results without taking up so much bandwidth.

   A quick update: The file was ‘approved’ at 8:30AM today. If you are interested in seeing it: http://www.mathworks.com/matlabcentral/fileexchange/23565 (I know, another shameless plug, but I figure this contest is also about marketing your submissions;)

   Alan, File Exchange submissions are generally reviewed at least once per business day. During the contest, we’re upping this frequency, but will still not be instantaneous. Thanks for your patience.

   With respect to the video size, I think the “‘compression’, ‘None’” is what is inflating the size so much. You might experiment with a combination of available “Compression” codecs and “Quality” to get acceptable results with reasonable file size.
