I understand that you can launch MATLAB from terminal. Make sure that you can launch MATLAB anywhere on your system by executing “matlab” command in terminal.
If not, you can create a symbolic link for the same. As you have installed MATLAB in a different directory, you can use -
sudo ln -s <YOUR_MATLAB_LOCATION>/bin/matlab /usr/local/bin/matlab
Assuming symbolic link is working, in Ubuntu 20.04 you can make a launcher by copying the desktop file from
Your matlab.desktop should have a similar structure -
Comment=Start MATLAB - The Language of Technical Computing
#Uncomment the following line and comment the line after to
#force matlab to use the 32 bits architecture
#Exec=matlab -arch=glnx86 -desktop
#Uncomment the following line if you've got several matlab icons in the launcher
You’ll have to make it executable by running
You should be able to locate the MATLAB launcher in the dash now.
Hope this helps.
