of the second processor. Mathworks has a page that discusses this a
bit:
http://www.mathworks.com/support/solutions/data/27619.shtml
there's also a short essay by Cleve Moler on why there isn't a parallel
version of MATLAB:
www.mathworks.com/company/newsletter/ pdf/spr95cleve.pdf
It's also worth noting that there are benefits to a second processor
even if all of your apps are single-threaded, e.g., you can listen to
MP3's without skipping while MATLAB is crunching away.
