function varargout = exp1_gui(varargin) % EXP1_GUI MATLAB code for exp1_gui_timer.fig % EXP1_GUI, by itself, creates a new EXP1_GUI or raises the existing % singleton*. % % H = EXP1_GUI returns the handle to a new EXP1_GUI or the handle to % the existing singleton*. % % EXP1_GUI('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in EXP1_GUI.M with the given input arguments. % % EXP1_GUI('Property','Value',...) creates a new EXP1_GUI or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before exp1_gui_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to exp1_gui_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
