@yixiao wu: And did you read my answer already? This is not a bug or a problem, but it means, that the license you have installed will expire. The message explains exactly, what you have to do:
contact your system administrator or The MathWorks to renew this license

Hi, this question was raised already some time ago. Nevertheless for those who are new to Matlab and receive this message 'Your Matlab license will expire in XX days.' in their command window, here is the solution for students and university members:
The message appears because your institute has a contract with matlab for a campus-wide license. From time to time it is necessary to validate that you are still a student or university member and here is how it goes:
Start Matlab and click on the HOME-tab and then on the Help-button (below the question mark)
A drop-down menu appears: choose > Licensing > Activate Software
Allow Matlab to make changes on your computer
(if not possible start Matlab in administrator mode)
Choose: Activate automatically using the Internet (recommended)
click on next
Choose: Log in to my MathWorksAccount: type in your email address and your password.
click on next
Select the license you want to renew, e.g. Academic License (Uni XY).
click on next
A prompt appears:
"You must verify your university login information before you can proceed.
Click here to complete the verification process from your university's login portal."
> Click on the blue words "click here" to follow the link to your university/institute website.
Login with your university/institute account in order to confirm your membership.
aftwards your forwarded to the MathWorks page displaying: "Verification succesfull"
Go back to matlab and click on OK in the promt window.
click on next
Type in the name of the Windows/Mac/Linux user for whom the license should be valid
(depending on the contract the license is only valid for one or two users).
click on next
This information will be sent to MathWorks.
click on confirm
Activation is complete > click on Finish.
Close your browser window, close Matlab.
Your license is now prolonged.
If the message "Your Matlab license will expire in XX days" still appears after restarting Matlab,
click on the Help button (in the HOME-tab) and choose Licensing -> Update current License from the drop-down menu.
After the next restart of Matlab the message should be gone.

Hi all, just wanted to add another approach that worked for me. In the toolbar, I chose help-> Licensing->update current licensing. Then in the pop-up window I clicked update. It got updated, restarted matlab and everything worked fine. This is for university type licensing.

The next question, which concerns a license, which expires on the 11-Nov-2017. See https://www.mathworks.com/matlabcentral/answers/356845-plz-help-me-all. I'm afraid we are getting more of them in the next weeks.
The message is clear already:
Please contact your system administrator or The MathWorks
Of course the public forum cannot help you directly, but you have to contact MathWorks officially to buy a new license. Use the "Contact Us" link on the top of this page or contact the sales team directly: Sales Team

Hi Anam,
This occurs when your MATLAB license file is set to expire for one of several possible reasons. Simply re-activate MATLAB if you still have a valid license. I have attached a link below to our article that explains this message and resolution.
Why do I receive a message that MATLAB will expire in XX days?
