# Unzip the installer file using this command: (or right click -> extract here)
unzip -X -K matlab_R2020a_glnxa64.zip -d matlab_2020a_installer
# Open the matalab_2020a_installer folder and open a terminal
# use your terminal as root  using the following command : (required to let MATLAB write in usr directory)
sudo su
# type your password then :
sudo ./install
# Be sure to create a symbolic link, so you can start it using "matlab -desktop", if you forgot this, you can create it manually by doing "sudo ln -s /usr/local/MATLAB/R2020a/bin/matlab /usr/local/bin/matlab"
