v = class( struct( ‘size_’, s, ‘basis_’, b, ‘dual_’, ‘’, ‘dof_’, d, ‘slow_’, slow ), ‘cvx’, cvxobj );
Please tell me how to solve it, thanks

What is the output of

Try a new MATLAB session.
Try reinstalling CVX (install version 2.2)

Can you successfully run any CVX program?

I installed CVX (install version 2.2)
Cannot run MIP,Some examples can be run
I can find this directories E:\work\hanhan\cvx\cvx\sedumi.travis.yml
But matlab cannot be searched

If you have tried: new MATLAB session, reinstall of CVX, and rebooting the computer, and the error still occurs, I suggest you file a bug report per .

I wouldn’t worry about

WARNING: The following files/directories are missing:

Many (all?) people get that warning, with no apparent harm.

May I ask if your problem has been resolved? I also encountered a problem where the file displaying: D:\Software\matlab2020b\cvx\sedumi.travis.yml is missing. I hope to receive your reply! Thanks!

I think you can just ignore that message, un less you encounter some other error.
