1. Prompt for no access during installation
open the install file with sudo command, and remember to CD to the install directory

 sudo ./install

if the program is stuck and cannot be opened after entering the password, open the terminal and enter the following command

xhost +SI:localuser:root

2. Prompt for no access when installing the toolbox using the built-in add on
use Chmod to adjust file access rights

sudo chmod -R o+rw /usr/local/MATLAB/RXXXXx

after adjusting the permissions, you can download it, but an unexpected error appears at the end, which makes it impossible to install it
download the MATLAB installer again and reinstall it. Note that you don’t need to reinstall it all. Just select the toolbox you want
