% COM_TO_MATLAB_2011_07_03 MATLAB code for com_to_matlab_2011_07_03.fig
%      COM_TO_MATLAB_2011_07_03, by itself, creates a new COM_TO_MATLAB_2011_07_03 or raises the existing
%      singleton*.
%
%      H = COM_TO_MATLAB_2011_07_03 returns the handle to a new COM_TO_MATLAB_2011_07_03 or the handle to
%      the existing singleton*.
%
%      COM_TO_MATLAB_2011_07_03('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in COM_TO_MATLAB_2011_07_03.M with the given input arguments.
%
%      COM_TO_MATLAB_2011_07_03('Property','Value',...) creates a new COM_TO_MATLAB_2011_07_03 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before com_to_matlab_2011_07_03_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to com_to_matlab_2011_07_03_OpeningFcn via varargin.
