Matlab upgrade release
Matlab version upgrade and AddOns installer was significantly changed in Matlab R2025a. Matlab release upgrades can be initiated from the “bell” icon or from the Matlab Help menu. Upgrading or Add-On install requires a graphical connection to the computer (Remote Desktop, VNC, or similar). Offline installs are considerably more complex and are not for the typical Matlab user.
Matlab release upgrade
The bell icon on the upper right corner of the Matlab Desktop typically shows when a Matlab update is available. Matlab can force checking for update, even if the bell is not showing an update, with our script MatlabReleaseUpgrade.m.
Matlab Add-Ons and mpm CLI installer
Matlab Add-On Explorer is launched from the Matlab Desktop and requires a graphical connection. The mpm CLI installer can be used to install Matlab and Add-Ons from the command line.
Troubleshooting
If the graphical connection has a problem like:
terminating with uncaught exception of type (anonymous namespace)::DisplayError: No display available.
try making a graphical UI window like:
h = uihtml(HTMLSource=which('peppers.png'), Position=[0,0,512,384])This should show the Peppers image including with Matlab.
If on Linux with a graphical connection and errors result, try prioritizing system libcrypto.so like:
LD_PRELOAD=/path/to/libcrypto.so matlabRelated: Matlab install on Linux
