```
cvx_begin sdp
variable P(4,4) symmetric
variable R(3,2)
variable H(1,2)
p11=P(1:3,1:3);p12=P(1:3,4);p22=P(6);
y1=p11*R+p12*H;
y2=p12'*R+p22*H;
cvx_end
```

R and H are known matrices with appropriate dimension. but I have following error:

Error using * (line 126)

Disciplined convex programming error:

Only scalar quadratic forms can be

specified in CVX

.

Error in cvX (line 23)

`y1=p11*R+p12*H;`

So what’s worng?
