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