================================================================

Matlab默认的绘图窗口是自动的，要想窗口初始最大化，有以下几种方法：

1.

figure;
set(gcf,'outerposition',get(0,'screensize'));

2.

a=get(0);
figure('position',a.MonitorPositions);

3.

set(gcf,'Position',get(0,'ScreenSize'))

总结：这里涉及到了MATLAB句柄的使用，以及"0”作为根句柄的规则。

================================================================

有时我们绘图希望figure直接最大化、甚至全屏，虽然用的不多，但是需要用来还真不是一个小问题哦！ （1）最简单的方法就是设置的figure的outerposition或者position属性为screensize，这个方法并非真正的 最大化，只是调整了figure的大小和坐标而已！ sz=get(0,'screensize'); figure('outerposition',sz); 复制代码 （2）地球人都知道，matlab是使用Java做框架和界面，于是只要从Java入手，应该可以毫无压力的搞定这些 日常操作： h=figure; jFrame=getJFrame(gcf); %或者jframe=getJFrame(h);  jFrame.setMaximized(1); %最大化figure jFrame.setMinimized(1); %最小化figure jFrame.setAlwaysOnTop(1); %将figure置顶 复制代码 需要用掉下面的getJFrame.m代码，具体可以查看这里，另外感谢junziyang编写getJFrame函数！ function JFrame = getJFrame(hfig) error(nargchk(1,1,nargin)); if ~ishandle(hfig) && ~isequal(get(hfig,'Type'),'figure')     error('The input argument must be a Figure handle.'); end mde = com.MathWorks.mde.desk.MLDesktop.getInstance; if isequal(get(hfig,'NumberTitle'),'off') && isempty(get(hfig,'Name'))     figTag = 'junziyang'; %Name the figure temporarily     set(hfig,'Name',figTag); elseif isequal(get(hfig,'NumberTitle'),'on') && isempty(get(hfig,'Name'))     figTag = ['Figure ',num2str(hfig)]; elseif isequal(get(hfig,'NumberTitle'),'off') && ~isempty(get(hfig,'Name'))     figTag = get(hfig,'Name'); else     figTag = ['Figure ',num2str(hfig),': ',get(hfig,'Name')]; end drawnow %Update figure window jfig = mde.getClient(figTag); %Get the underlying JAVA object of the figure. JFrame = jfig.getRootPane.getParent(); if isequal(get(hfig,'Name'),'junziyang')     set(hfig,'Name',''); �lete the temporary figure name end 复制代码 （3）另外在调整figure窗体的位置时，我们可以能需要用到一个movegui()函数，这个函数的功能就是 将figure平移到某个位置，但是不调整figure窗口的大小，具体用法可以参考matlab的帮助。 （4）在Window中Figure无非就是一个窗口，显然我们可以通过Window API对这个窗口进行操作 plot(1:5,1:5) maximize 复制代码 对应需要调用maximize.m函数以及DLL动态链接库（ http://www.matlabsky.com/static/image/filetype/zip.gif maximize.zip (4.21 KB, 下载次数: 60) ） function maximize(h) % MAXIMIZE   maximize figure windows % ==================================================================== % %        Berne University of Applied Sciences % %        School of Engineering and Information Technology %        Division of Electrical- and Communication Engineering % % ==================================================================== %                       maximize figure windows % ==================================================================== % % Author:    Alain Trostel % e-mail:    alain.trostel@bfh.ch % Date:      June 2007 % Version:   4.1 % % ==================================================================== % % function maximize(h) % % Input parameters % ----------------- %   h             handle(s) of the figure window % % % Output parameters % ------------------ %   The function has no output parameters. % % % Used files % ----------- %   - windowMaximize.dll % % % Examples % --------- %   % maximize the current figure %   ------------------------------ %   maximize; % % %   % maximize the current figure %   ------------------------------ %   maximize(gcf); % % %   % maximize the specified figure %   -------------------------------- %   h = figure; %   maximize(h); % % %   % maximize the application window %   ---------------------------------- %   maximize(0); % % %   % maximize more than one figure %   -------------------------------- %   h(1) = figure; %   h(2) = figure; %   maximize(h); % % %   % maximize all figures %   ----------------------- %   maximize('all'); % % %   % maximize a GUI in the OpeningFcn %   ----------------------------------- % %   % --- Executes just before untitled is made visible. %   function untitled_OpeningFcn(hObject, eventdata, handles, varargin) %   % This function has no output args, see OutputFcn. %   % hObject    handle to figure %   % eventdata  reserved - to be defined in a future version of MATLAB %   % handles    structure with handles and user data (see GUIDATA) %   % varargin   command line arguments to untitled (see VARARGIN) % %   % Choose default command line output for untitled %   handles.output = hObject; % %   % Update handles structure %   guidata(hObject, handles); % %   % UIWAIT makes untitled wait for user response (see UIRESUME) %   % uiwait(handles.figure1); % %   % maximize the GUI %   set(hObject,'Visible','on'); %   maximize(hObject); % check if dll-file exists if ~exist('windowMaximize.dll','file')     error('windowMaximize.dll not found.'); end % if no input parameters, get handle of the current figure if nargin == 0     h = gcf; end % if one input parameter, check the input parameter if ischar(h)     % check the string     if strcmpi(h,'all')         % get all figure handles         h = findobj('Type','figure');                 else         % incorrect string argument         error('Argument must be the correct string.');     end else     % check each handle     for n=1:length(h)         % it must be a handle and of type 'root' or 'figure'         if ~ishandle(h(n)) || (~strcmp(get(h(n),'Type'),'root') && ...                                ~strcmp(get(h(n),'Type'),'figure'))             % incorrect handle             error('Argument(s) must be a correct handle(s).');         end     end end % if handle is not the root if h ~= 0     % for each handle     for n=length(h):-1:1         % create the temporary window name         windowname = ['maximize_',num2str(h(n))];         % save current window name         numTitle = get(h(n),'NumberTitle');         figName = get(h(n),'Name');         % set the temporary window name         set(h(n),'Name',windowname,'NumberTitle','off');         % draw figure now         drawnow;         % maximize the window with the C function         windowMaximize(windowname,get(h(n),'Resize'));         % reset the window name         set(h(n),'Name',figName,'NumberTitle',numTitle);     end else     % maximize the application window "MATLAB"     windowMaximize('MATLAB'); end 复制代码 （5）这里还有一个通过API函数实现的Figure操作， http://www.matlabsky.com/static/image/filetype/zip.gif AlterWindow.zip (1.54 KB, 下载次数: 19)  MEX-file to affect windows, e.g. maximize, minimize, hide, show, etc. To compile use >> mex AlterWindow.c user32.
