i am trying to install matlab on my new ubuntu 20.04 pc, but i cant even get the installer to show up
i am following the instructions from here, but when i enter the 'sudo ./install' command on the terminal nothing seems to be happening (whereas i ender the './install' command, without sudo, the window shows up instantly). the terminal just seems to get busy but doesn't produce any results
i also tried to change the access permisions on the directory where the installer is with chmod but that doesn't seem to change anything
do i just have to wait for it to load? shouldn't it open in less than a minute? thanks.

There seems to be a bug in the installer for Linux. You can run it without sudo, but you will have to chown the installation directory to the current user (and back to root).

From a comment deep in the thread (here), and from reading your symptoms, what typically works with this version of Ubuntu is:
xhost +SI:localuser:root
sudo ./install

Having Matlab in /usr/local comes with additional issues--namely, Matlab can't modify itself (e.g., installing Add-ons) without permissions changes. Should you need additional Add-ons, the safest method I'm aware of would be to re-run the installer.

alright, after reading the thread you linked and messing around a bit i finally managed to figure it out. thanks again for your help!!
(if anyone needs to know, i made the file ~/.local/share/applications/matlab_r2021b.desktop with the following contents:
#!/usr/bin/env xdg-open
[Desktop Entry]
Version=R2021b
Type=Application
Terminal=false
Exec=/usr/local/MATLAB/R2021b/bin/matlab -desktop
Name=matlab
Comment=R2021b
Icon=/usr/local/MATLAB/R2021b/bin/glnxa64/cef_resources/matlab_icon.png
and then made it executable with chmod +x ~/.local/share/applications/matlab_r2021b.desktop
then i searched for 'matlab' in my apps and it showed up)
