matlab实验,二话不说,放图

三、详细设计

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. Choose "GUI allows only one

% instance to run (singleton)".

% See also: GUIDE, GUIDATA, GUIHANDLES
