I want to obtain X,Y and mu in the picture. My code is attached bellow.

```
A=[-1,2;-3,4];B=[0.5;-2];Bw=[0;1];
cvx_begin sdp
variable X(2,2) symmetric;variable Y(1,2);variable lambda0;variable mu1;
subject to
[(A*X+B*Y)'+A*X+B*Y+lambda0*X,Bw;Bw',-mu1*eye(1)]<=0;
X>=0;lambda0>=0;mu1>=0;
cvx_end
```

Disciplined convex programming error:

Invalid quadratic form(s): not a square.

It shows the error above and I find out lambda0*X goes wrong. But How can I solve this problem?
