By the way,the cvx’s path is e:/cvx, how can I solve this problem?

Try and try again,I find the problem was caused by anti-virus software , then shut down it and restart Matlab!

Interesting! I’m glad you solved it. But I wonder how the antivirus software could impact Matlab scripts? I’m unfamiliar with that.
