I am Miriana Fiammingo, a student of Politecnico di Torino.
I installed Matlab on my PC but when I open the software it gives me problems about the license, with error -9. How can I solve this? Thank you.

License error 9 occurs when MATLAB is activated by different user account from the account you're currently using and here is an answer. How about deactivate and activate again?
Double click $MATLAB\uninstall\bin\win64\deactivate_matlab.exe and deactivate MATLAB first.
Then, launch MATLAB again. It will ask you to activate.
