Problem with relase YALMIP and relase Matlab

[Monika Rybczak]

Good morning.

Of course I have question about commend in Yalmip. I have two versions YAlmip for Matlab 2012b and Matlab 2016b. I  will have change file in version 2012b who will be working for Matlab 2016b and in this version my file don't work. And I know (I read in this forum) command "set" is obselve and I change this for "nothing", the same I change "solversdp" for "optimize". And of course I change solver SeDuMi 1.3 for Mosek (very nice solver). But I have conflikt and please help me beacuse I have'nt know what is wrong in my commend list, please check (I write comment line (%) which work in Matlab 2012b, with SeDuMi 1.3 for yalmip)

Ag1 =[ -0.0000         0         0   -0.2500         0         0

yalmip('clear');

X=sdpvar(6,6,'symmetric');

Y=sdpvar(3,6);

W1=Ag1*X+Bg12*Y;

%F=set ('X > 0');

F=('X > 0');

%F=F+('kron(PP,X)+kron(QP,W1)+kron(QP'',W1'') <= 0');

F=('kron(PP,X)+kron(QP,W1)+kron(QP'',W1'') <= 0');

gam=1.65;   %2.1

W21a=Cinf*X+Dinfu*Y;

%F=F+set('[W1+W1'' Bw W21a''; Bw'' -gam^2*eye(3) Dinfw''; W21a Dinfw -1*eye(3)] <= 0');

F=('[W1+W1'' Bw W21a''; Bw'' -gam^2*eye(3) Dinfw''; W21a Dinfw -1*eye(3)] <= 0');

Q=sdpvar(n,n,'symmetric');

W33a=C2*X+D2u*Y;

W33b=Ag1*X+Bg12*Y;

F=('[W33b+W33b''+Bw*Bw''] < 0');

F=F+set('[W33b+W33b''+Bw*Bw''] < 0');

%F=F+set('sqrt(trace(Q)) => gam^2');

F=('sqrt(trace(Q)) => gam^2');

ops=sdpsettings('solver','mosek','verbose',0);

%sol=solversdp(F,gam+trace(Q),ops);

(298) sol=optimize(F,gam+trace(Q),ops);

Then I have that answer:

Error using solvesdp (line 78)                                                  ------ this error is very strange beacuse i don't use this command in my file, this error is link with file solversdp.m

First argument (F) should be a constraint object.

Error in optimize (line 31)

[varargout{1:nargout}] = solvesdp(varargin{:});

Error in Control_KK_for_Mosek_Matlab2016b (line 298)              ---- this error deal with my file Control_KK_for_Mosek_Matlab2016b

sol=optimize(F,gam+trace(Q),ops);

This is very important to my file...please check and answer to me ...I will hope this is very simple :)
