I checked at my University and they do not have a Matlab .iso
file for Ubuntu.
Where can I get this?
Sure, you can get it from the MATLAB MathWorks site.
You need to login to use this, so you should have a University account that can be used.
If not, you can ask the University to download it for you, and give them a USB for it.
Most unfortunately, MatLab is neither open software nor free. You could check with the University to see who holds the license to MatLab, and ask them to download the ISO file.
