hello,can you help me with this SDP pronlem? as i know, my optimization problem is convex and i want to solve it with CVX. I don’t know my code is right or not, although it has solved this problem. Can you help me? Thank you.

I don’t see anything obviously wrong, but i also don’t know for sure what all the notation means, and how your input data maps to it, including the calculations made prior to CVX. Of course you are using \sigma_n^2 = 0.

Also:
This is not a TFOCS problem.

In the future, please copy and paste code into your post and use the Preformatted text icon rather than posting an image code. This allows forum readers to copy and paste your code into their own MATLAB session.

@jifazhang I may have inadvertently deleted a change you made which was in the moderator queue. Please try again to post it.

ok, i will try again, i have known that my code is right, thank you very much.
