Update Your License

Automatic License Updates

Throughout the term of your license, your MATLAB®installation periodically contacts MathWorks®to verify that your license is up to date. If your license is up to date, the validation process is transparent. If it determines that you need to update your license, the validation process displays a dialog box giving you the option to update your license.

你可以禁用验证的License Centerat the MathWorks website.

Update License Manually from WithinMATLAB

To update your license manually from within MATLAB:

  1. On theHometab, in theResourcessection, clickHelp>Licensing.

  2. SelectUpdate Current Licenses...and follow the prompts to update your license.

MATLAB contacts MathWorks to retrieve the most current version of the License File for the license. The update process overwrites the current License File on your system. You need to restart MATLAB.

Update License Using Activation

If your license file has expired or another licensing requirement is preventing MATLAB from starting, you can update your license by using the MATLAB activation client.

For instructions on using the activation client, seeActivate MATLAB Installation Manually.

Update License for Offline Computer

If the computer that is running MATLAB cannot connect to the Internet, you can download a license file manually from the MathWorks website on another computer and move the file to the target computer.
