国外专家做的求解LMI鲁棒控制的工具箱,可以相对高效的解决LMI问题

function F = set(varargin)
%CUT               Defines a cut constraint
%   
% The syntax for CUT is exactly the same as the
% syntax for SET. In fact, the result from CUT is
% a SET object.
%
% The difference between a ordinary constraint and 
% a cut constraint is that the CUT will not be used
% in the solution of the upper bound problem in a
% global solver, but only in the relxation for the 
% lower problem.

%    See also   SET
