Get Update of Installed MATLAB Release
Download and install a more recent version for the release of MATLAB® that you currently have installed. For example, if you have R2023b installed, you might be able to download a more recent version of R2023b.
When you install a MATLAB update, you get not only the most recent update for your version, but also all prior updates for your version as well.
Update from Notifications in MATLAB
If a more recent version is available, a notification displays in MATLAB when you start the program.
To install the MATLAB update, click the notification icon and select Install Update. If you click the notification and then decide to update at a later time, the notification icon is no longer red, but you can still install the update.
Check for Updates
You can also check for updates manually.
Make sure that you have an active Internet connection.
On the Home tab, click Help > Check for Updates. The Add-On Manager opens with the Updates tab selected.
If an update is available, click the Update button to the right of the update name to install it. If no update is available for your version or if you have already installed the latest update, MATLAB displays that information.
