function varargout = net1(varargin) % NET1 M-file for net1.fig % NET1, by itself, creates a new NET1 or raises the existing % singleton*. % % H = NET1 returns the handle to a new NET1 or the handle to % the existing singleton*. % % NET1('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in NET1.M with the given input arguments. % % NET1('Property','Value',...) creates a new NET1 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before net1_OpeningFunction gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to net1_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
