I typed the code bellow:

```
%%
% C=
% 1
% 0
% 0
% 0
% 0
% 0
% 0
% 0
% 0
% 0
Qt=(F'*F+Q ); % F is a 10*10 complex matrix
bi=F'*C;
a_trgt=( F(1,:) ).'; % Target constraint at the first row of F matrix
cvx_begin sdp
variable mu1(1)
variable tiii %% quasiconvex form : substituting {minimize(p(x)/q(x) su)p}
minimize ( ( bi'*( inv(Qt) * a_trgt*a_trgt' * inv(Qt) )*bi / (a_trgt'*inv(Qt)*a_trgt)) * inv_pos( (1+mu1*(a_trgt'*inv(Qt)*a_trgt))) + mu1 );%
subject to
( Qt+ mu1*(a_trgt*a_trgt') ) > 0
cvx_end
%%
```

but i received bellow error :

```
Error using cvx/pow_cvx (line 144)
Disciplined convex programming error:
Illegal operation: pow_p( {complex affine}, {-1} )
Error in cvx/inv_pos (line 5)
y = pow_cvx( x, -1, 'pow_p' );
```

what is wrong in this structure? I think the objective function is convex and there should be no problem. Am i right?
