solvesos type diagnostics from optimize or optimizer?

[gyi]

Is it possible to get diagnostics (sol), Q, or residuals from optimize and/or optimizer as I am able to do from solvesos?

[sol,m,Q,residuals,everything] = solvesos(F,obj,options,params,candidateMonomials)

Thanks.

No

well, diagnostics of  course, as it is the seond output from the optimzer call as always

I suppose I can find residuals manually using  check?

No, the internal structures are not updated when optimizer is used (it does as little as possible while still trying to return the data you say you are interested in). You would have to do some pretty advanced programming

sdpvar x t a
p = x^2-a*x; % Check lower bound of this w.r.t a
[F,obj,monoms,etc] = compilesos(sos(p-t),-t,sdpsettings('sos.model',2,'sos.scale',0),[a;t]);
sossolver = optimizer(F,obj,sdpsettings('solver','mosek'),a,{t,etc.BlockedQ{1}{1}});
sol = sossolver{0};
coefficients(replace(p,a,0)-sol{1})-monoms{1}'*sol{2}'*monoms{1},x)
