What does theis error mean?

What s the output of cvx_version ?

Can you run any problem successfully in CVX? Have you tried cvx_solver sdpt3 ?

Try a fresh MATLAB session - maybe your current session got corrupted somehow. If that doesn’t eliminate the error, try removing all CVX directories from the MATLAB path, and reinstall CVX in a fresh MATLAB session. Make sure you install CVX 2.2

cvx version is CVX 2.2
Yes, I can run any problem.
I tried cvx_solver sdpt3 but this is the output doesn’t make sense:
Status: Unbounded
Optimal value (cvx_optval): -Inf

That output says that CVX/solver concluded the problem is unbounded. Try following the advice at https://yalmip.github.io/debuggingunbounded , which also applies to CVX.
