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