出错 cvxprob/solve (第 354 行)

I saw the question in the forum that it was the CVX version, but my CVX is 2.2, so I don’t know what to do, I hope people who know this can answer my confusion, thank you!!

Here’s my CVX version

You can try:

New MATLAB session.

Reinstalling CVX 2.2 Or try CVX 2.2.2 Announcement: CVX 2.2.2, the first "full" open-source release

[ls1128uhbdnjnefk]

Thank you very much for your reply, I will try this method

Or perhaps it’s a bug in CVX.

Error during execution

When I ran the code, I am getting the following error: Undefined function or variable ‘last_act’. Error in cvx_solve (line 315) if ~found && last_solved == solved && last_act == nact, Error in cvx_finish Error in cvx_end (line 11) evalin( ‘caller’, ‘cvx_finish’ ); Error in Scenario2_multiplesubchannelsperD2D (line 109) cvx_end how can I rectify it.
