I'm just using R13 now, as my employer doesn't have a later version.
At school I use R14SP3, I think, but that doesn't help me much.
I've kind of put this part of my project on the back burner for now,
though I keep making other things work so I'll probably be back to
this in another day or two, heh.
I'm curious if there is a hidden feature that Matlab uses to do this,
that we might be able to (in a rather ugly manner) hitch onto and use
for our own purposes.
