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