Hi everyone. I should resolve this problem in cvx, so I wrote in matlab:

```
cvx_begin sdp
variable Q(T,2)
variable a(1,1)
[Z0T*Q-a*(Z1T*Z1T') Z1T*Q; Q'*Z1T' Z0T*Q]>=eye(4)
[eye(T) Q; Q' Z0T*Q] >= eye(9)
cvx_end
```

In particular:

-a is a scalar

-Q a matrix Tx2

-Z01 and Z1T matrices 2xT

The result is NaN. I have committed some mistakes?
