Hi, I have problem on my cod I want to ask you if it is possible please help me.

I have error as

"Error using reshape

Size arguments must be real integers.

Error in cvx/cat (line 93)

x = reshape( x, numel(x) / rsiz, rsiz );

Error in cvx/vertcat (line 6)

y = cat( 1, varargin{:} );

"

and mu code is

%%%%%%%%%%%%%%%%%%%%%%%%

cvx_begin sdp

variable L1(2,1)

variable Ahat(2,2)

variable sigma1(4,4) symmetric

%%

Abar=[A zeros(2,2);A-L1*H -(Ahat-L1*H)];

Bbar=[B zeros(2,1);B -L1];%4*2
Hbar=[H1;H1-L1*H

*H2]*

Ebar=[E zeros(1,2)];

Q=sqrt([0.00125eye(2,2) zeros(2,1);zeros(1,2) (0.00125)]);

Ebar=[E zeros(1,2)];

Q=sqrt([0.00125

%% cost function

minimize (trace(sigma1))

%% LMI

[sigma1 sigma01

*Abar’ Bbar*Q sigma01*Ebar’

```
(sigma01*Abar')' sigma01 -alpa*(Hbar*Hbar') zeros(4,3) zeros(4,1)
(Bbar*Q)' zeros(3,4) eye(3,3) zeros(3,1)
(sigma01*Ebar')' zeros(1,4) zeros(1,3) alpa
]>=0
cvx_end
```

I couldn’t understand what is the error?
