% STATE_FEEDBACK_GUI M-file for state_feedback_gui.fig
%      STATE_FEEDBACK_GUI, by itself, creates a new STATE_FEEDBACK_GUI or raises the existing
%      singleton*.
%
%      H = STATE_FEEDBACK_GUI returns the handle to a new STATE_FEEDBACK_GUI or the handle to
%      the existing singleton*.
%
%      STATE_FEEDBACK_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in STATE_FEEDBACK_GUI.M with the given input arguments.
%
%      STATE_FEEDBACK_GUI('Property','Value',...) creates a new STATE_FEEDBACK_GUI or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before state_feedback_gui_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to state_feedback_gui_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
