% Main script files:
% SCDOPE : Erroneous answers from the CDOPE (Conventional Discrete-time Optimal
% Projection Equations) and correct answers from the SDOPE (Strengthened
% Discrete-time Optimal Projection Equations) of example 1 in the paper.
% EXAMP2 : Results of example 2 in the paper.
% EXAMP3 : Results of example 3 in the paper.
%
% Main functions:
% DPROTIN : Deterministic Parameter Reduced-Order Time-Invariant iNfinite horizon LQG compensation.
% Optimal compensation of (P,G,C,V,W) based on (Q,R) and nc<=nx.
% (P,G,C) deterministic. Based on the SDOPE.
% DPROTINO: The same but based on the CDOPE that provide erroneous answers!
% DPROEQ : One iteration of the SDOPE.
% DPROEQO : One iteration of the CDOPE that provide erroneous answers!
% GMHFAC : gmh alpha factorization of ph*sh, ph>=0, sh>=0, ph=ph', sh=sh',
% r=rank(ph)=rank(sh) (=rank(ph*sh))
