%SOSMODEL Derive sum-of-squares model without solving it
|
|
%
|
|
% [F,obj,m] = sosmodel(F,h,options,params,monomials) compiles the SOS
|
|
% problem (i.e., derives the SDP model) without actually solving it
|
|
%
|
|
% Inputs
|
|
% F : The model involving SOS constraints
|
|
% h : Objective function (function of params) [optional]
|
|
% options : SDPSETTINGS structure [optional]
|
|
% params : Parametric variables in model [optional]
|
|
% monomials : Prespecified monomials to be used [optional]
|
|
%
|
|
% Outputs
|
|
% F : Constraints defining the problem
|
|
% h : Objective function
|
|
% m : Monomials used in the decomposition
|
|
%
|
|
%
|
|
% NOTE: If you do not specify any options structure or specify sos.model
|
|
% as default 0 an image model representation will be used (sos.model = 2).
|
|
% With this, the compiled model is expressed in terms of the original
|
|
% variables (with kernel model, a dual problem is derived, and thus no
|
|
% original variables are used)
|
|
%
|
|
% See also SOLVESOS, OPTIMIZE, SOS, OPTIMIZER
|
|
|
|
% When sosmodel is used, default is to return a model expressed in the
|
|
% original variables, i.e., image space model
