% EXPERIMENT04 MATLAB code for experiment04.fig
% EXPERIMENT04, by itself, creates a new EXPERIMENT04 or raises the existing
% singleton*.
%
% H = EXPERIMENT04 returns the handle to a new EXPERIMENT04 or the handle to
% the existing singleton*.
%
% EXPERIMENT04('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in EXPERIMENT04.M with the given input arguments.
%
% EXPERIMENT04('Property','Value',...) creates a new EXPERIMENT04 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before experiment04_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to experiment04_OpeningFcn via varargin.

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
