Update an Existing Installation
You can download and install a more recent version of the release of MATLAB® that you currently have installed. For example, if you have R2020a installed, you might be able to download a more recent version of R2020a. This version is called a MATLAB update. When you install a MATLAB update, you get not only the most recent update for your version but also all previous updates for your version as well.
Update from Notifications
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 then select Install Update. If you click the notification but decide not to install the update, the notification is cleared; however, you can still install the update at a later time.
Check for Updates
You also can check for updates manually. You must have an active internet connection to check for and update your installation.
On the Home tab, click Help > Check for Updates. The Add-On Manager opens with the Updates tab selected. If there is an update available for your version of MATLAB, click the Update button to the right of the update name to install it. If there is no update available for your version or if you have already installed the latest update, MATLAB displays that information.
In R2019a: On the Home tab, click Help > Check for Updates > Products. If there is an update available, click Install Update.
Before R2019a: On the Home tab, click Add-Ons > Check for Updates > Products.
