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