MIMO系统的DEMO

%LOGREPORT Create simulation log-file.
%   LOGREPORT simply archives simulation environment variables and
%   running conditions into a log-file named `mimotools.log'. In fact 
%   LOGEPORT script is a part of the main MIMO script and therefore it 
%   must not work when running alone. 
%   
%   See also MIMO, MESG, POST.
