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