@Eren Gündüz that depends on the university. Some of them are configured that way, but for others you need to get the license from staff, and for other universities you need to buy individual licenses.

In some cases there is confusion between the license itself expiring, compared to Software Maintenence Service (SMS) expiring. SMS is the right to use new releases, and the right to use some online software, and (for some kinds of account) the right to make technical support calls. When SMS expires, the right to use MATLAB itself is not affected. Many licenses are "perpetual" -- you can use them indefinitely... you just do not get access to new versions if you do not pay SMS.
That said, some licenses do expire:
  • Home licenses: always perpetual
  • Student licenses: mathworks used to sell 8 month or 1 year licenses through campus bookstores, but I have not heard of that for a number of years and I do not know if that is still offered. The Student licenses purchased through the online store are Perpetual, but can only be used while the student is enrolled in an appropriate educational institution.
  • MOOC (Massive Open Online Courses): Always Term licenses. The people running the MOOC are responsible for providing updated licenses if there is an extension.
  • Standard (commercial / professional) licenses can be either Term or Perpetual. It is more common for Individual licenses to be Perpetual, but they could be Term. It is more common for places that have Term licenses to use Network license servers.
  • Educational licenses: when purchased by individuals or small departments, it is more common for the licenses to be Perpetual. Total Academic Headcount licenses (the kind of license that permits students to use university licences to access MATLAB) are, if I understand correctly, always Term licences. There is, though, a twist, that any one licenses assigned under a TAH master license might be required to renew access even though the overall license has not expired, as TAH are charged according to the estimated number of users, so universities have reason to check that people who were using a license still need the license.
If you have an Individual license directly from Mathworks, or you are faculty or student using a TAH educational license, then to renew your license file (after all appropriate fees have been paid), then in your command window go to the top right, RESOURCES -> Help -> Licensing -> Update current licenses
If you are an end-user using a network license server at a university or business, then you would not typically have to update your licenses; but if it ever turns out to be necessary, you would do that same Update current licenses .
If you are IT staff managing a network license server, then you would pay appropriate fees to Mathworks who would send you an updated license file, which you would merge into your existing network license file. On Unix type systems, you would then typically send a SIGHUP to the license manager daemon to get it to re-read the license file without terminating any existing sessions. I do not recall at the moment if there is a lmgrd command to tell the daemon to reread the file.

If you have any trial license file then the trial license keeps getting used until it expires, even if a real license is installed. If this might be happening to you, delete the trial license files.

If you have been using a trial license, it is best to delete (or rename) the trial license file, to prevent it from interfering with the real license. Information about your real license should have been sent to you when you made your purchase.

It looks to me as if you need to contact Mathworks Sales in Ireland if you want to purchase a license.
If you have an existing license but are having problems getting it to work, then please contact Mathworks Support.
