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.
Starting in R2019a, 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.
You also can check for updates manually. You must have an active internet connection to check for and update your installation.
If you are using R2019b or later, 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.
For R2016b through R2019a, on the Home tab, click Help > Check for Updates > Products or Add-Ons > Check for Updates > Products. The Check for Updates dialog box opens. If there is an update available, click Install Update to install the latest MATLAB product update for your version.
If there is no update available for your version or if you have already installed the latest update, MATLAB displays that information.
