Matlab upgrade from Terminal
Matlab version upgrade can be initiated from the system Terminal or from the Matlab Help menu. Running the upgrade or Add-On install requires a graphical connection to the computer (Remote Desktop, VNC, or similar).
Matlab release upgrade
The bell icon on the upper right corner of the Matlab Desktop typically shows when a Matlab update is available. To force checking for install, even if the bell is not showing an update, under the Matlab binary directory look for “MathWorksUpdateInstaller”
fullfile(matlabroot, "bin", computer("arch"))Matlab Add-Ons
Matlab Add-On Explorer is normally launched from the Matlab Desktop. The Add-On Explorer requires a graphical connection. To launch Add-On explorer from the Matlab binary directory look for executable “AddOnInstaller”
Troubleshooting
If the graphical connection has a problem like:
terminating with uncaught exception of type (anonymous namespace)::DisplayError: No display available.
try for diagnosis:
w = matlab.internal.webwindow('www.mathworks.com');
w.bringToFront();The first command (object instantiation) should not error. The method “bringToFront” should bring up a window if the connection / system allows.
If on Linux with a graphical connection and errors result, try renaming libcrypto.so.1.1 like:
r=$(matlab -batch "disp(fullfile(matlabroot, 'bin', computer('arch')))" | tail -n1)
mv libcrypto.so.1.1 libcrypto.so.1.1.bakRelated: Matlab install on Linux
