function varargout = Mat5_2(varargin) % MAT5_2 MATLAB code for Mat5_2.fig % MAT5_2, by itself, creates a new MAT5_2 or raises the existing % singleton*. % % H = MAT5_2 returns the handle to a new MAT5_2 or the handle to % the existing singleton*. % % MAT5_2('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in MAT5_2.M with the given input arguments. % % MAT5_2('Property','Value',...) creates a new MAT5_2 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before Mat5_2_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to Mat5_2_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
