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