# I can think of 3 valid ways to do this:
# 1. Parse the install directory and use a hard-coded table. However,
# complicated by the fact that there are SP versions and that every OS
# stores the directory in a different manner.
# e.g. 'R2013a' could be parsed in to '2013' and 'a' and this implies V8.1
# (take a look at http://en.wikipedia.org/wiki/MATLAB#Release_history)
# 2. Parse the Help command (matlab -h).
# Doesn't technically run Matlab but is a pain and I can't guarantee
# that all Matlab versions print the EXACT same message.
# e.g. R2013a doesn't print any version information using 'matlab -h'
# 3. Run Matlab itself and query it's 'version' command. Matlab
# documentation tells me that this command exists at least as far back
# as R14. This is the method I've chosen as it also allows me to query
# the 'computer' command which says which architecture Matlab is
# running (32 bit/64 bit). I created a short Matlab script to print
# the appropriate output to stdout
