I can not solve the following global optimization example on wiki

[jujie zhang]

Hi, 

On my MATLAB, I ran the following global optimization example on wiki:

yalmip('clear')
A = [-1 2;-3 -4];B = [1;1];
P = sdpvar(2,2);
K = sdpvar(1,2);
F = [P>=0, (A+B*K)'*P+P*(A+B*K) <= -eye(2)-K'*K];
F = [F, K<=0.1, K>=-0.1];
F = [F, 1000>=P(:)>=-1000];
options = sdpsettings('verbose',1,'solver','bmibnb');
solvesdp(F,trace(P),options);

But it does not work. The result is NaN for double(P).

Why?

Please read the last paragraph in the tutorial (and read the diagnostic information returned from solvesdp, you don't have a nonlinear SDP solver)
