The way I got it to work was to follow the instructions here. After running the command:

sudo /media/MATHWORKS_R2012A/install -glnx86 -v

if there are unmet dependencies it will complain about some library not found. Next, search for this library in Ubuntu's packages for your release (in this case saucy). Make sure to search the contents of the packages. After you find the package name, install it: (make sure to include the trailing :i386)

sudo apt-get install <package-name>:i386

For example:

I am using the Student version of 2011a and the required packages for me on Ubuntu 13.10 are:

sudo apt-get install libxtst6:i386 libXext6:i386 libxi6:i386 libncurses5:i386 libxt6:i386 libxpm4:i386 libxmu6:i386 libxp6:i386

Edit:


For installing the Student version of 2011a on Xubuntu 14.04 I had to also install the lib32stdc++6 package:

sudo apt-get install lib32stdc++6
