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