Hi I wrote this code on matlab:

```
cvx_begin sdp
variable W_1(M(mm),M(mm)) complex hermitian semidefinite;
variable W_2(M(mm),M(mm)) complex hermitian semidefinite;
maximize eta*real((trace(H_01*W_1)+trace(H_01*W_2)));
subject to
real((trace(W_1) + trace(W_2))) < P_w_max;
real((trace(H_cu_1*W_2) + sigma2_w)) < real(trace(H_cu_1*W_1))/saai_w(1);
real((trace(H_cu_2*W_1) + sigma2_w)) < real(trace(H_cu_2*W_2))/saai_w(2);
cvx_end
```

there is an error on Matlab on my constraints.the error says: â<â produces a value that might be unused. and also when i check my constraints after the end of cvx, the last two are false.
