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