Hi everyone,
I’ve recently tried installing CVX in Matlab but there is a problem with the licence. I placed cvx in the MATLAB folder as in the guide however I get these errors.
I have disabled the security features of MacOS, so now I am not shown the option of ‘Cancel’ or ‘Move to trash’ and the installation procedes, however due to the licence problem I was not able to install mosek or gurobi.
cd ~/MATLAB/cvx
cvx_setup

I even used the licence generator but still was not able to proceed since I get this message:
