但是没有一个解决我的问题。
figure('units','normalized','outerposition',[0 0 1 1])
或者对于当前图形：
set(gcf,'units','normalized','outerposition',[0 0 1 1])
我还使用了在FileExchange上使用Java编写的MAXIMIZE函数。这是真正的最大化。
想要实现最大化窗口（就像在OS X和Windows的用户界面中点击最大化按钮一样），您可以尝试以下方法，调用一个隐藏的Java句柄：
figure;
pause(0.00001);
frame_h = get(handle(gcf),'JavaFrame');
set(frame_h,'Maximized',1);
pause(n) 是必要的，因为上述代码跳出了 Matlab 的范畴，并运行在一个独立的 Java 线程上。将 n 设置为任意值并检查结果。计算机执行速度越快，n 可以设置得越小。
这里可找到完整的“文档”.
警告：JavaFrame图形属性将在未来版本中被删除。有关更多信息，请参见mathworks.com上的Java和ActiveX用户建议。 Matlab R2019b @ Win10 64位 - winkmal从R2018a开始, figure 和 uifigure 对象都包含一个叫做 WindowState 的属性。默认情况下，它被设置为 'normal'，但将其设置为 'maximized' 可以得到期望的结果。
总之:
hFig.WindowState = 'maximized'; % Requires R2018a
Making figures maximized by default is possible using:
set(groot, 'defaultFigureWindowState', 'maximized');
Maximizing all open figures is possible using:
set(get(groot, 'Children'), 'WindowState', 'maximized');
More information about 'WindowState' as well as other properties controlling figure appearance can be found in this documentation page.
export_fig工具。set(groot，'defaultFigureWindowState'，'maximized')； - Unknown123Figure Properties 文档 https://www.mathworks.com/help/matlab/ref/matlab.ui.figure-properties.html 中的 Window Appearance 部分，了解有关 WindowState 的更多信息。 - Unknown123h = figure; %// create figure and get handle
plot(1:10); %// do stuff with your figure
figure(h) %// make it the current figure
robot = java.awt.Robot;
robot.keyPress(java.awt.event.KeyEvent.VK_ALT); %// send ALT
robot.keyPress(java.awt.event.KeyEvent.VK_SPACE); %// send SPACE
robot.keyRelease(java.awt.event.KeyEvent.VK_SPACE); %// release SPACE
robot.keyRelease(java.awt.event.KeyEvent.VK_ALT); %// release ALT
robot.keyPress(java.awt.event.KeyEvent.VK_X); %// send X
robot.keyRelease(java.awt.event.KeyEvent.VK_X); %// release X
完成！窗口已最大化！
正如上面的作者所提出的那样, 如果你想模拟点击“最大化”窗口按钮，你可以使用下面的代码。与提到的答案不同的是，使用“drawnow”而不是“pause”似乎更正确。
figure;
% do your job here
drawnow;
set(get(handle(gcf),'JavaFrame'),'Maximized',1);
在我看来，将图形窗口最大化并不是以更高分辨率保存图像的最佳方式。
有关于打印和保存的图形属性。使用这些属性，您可以按照任何您想要的分辨率保存文件。为了保存文件，您必须使用print函数，因为您可以设置一个dpi值。所以，首先设置以下图形属性：
set(FigureHandle, ...
'PaperPositionMode', 'manual', ...
'PaperUnits', 'inches', ...
'PaperPosition', [0 0 Width Height])
其次，将文件保存为png格式，并设置分辨率为100dpi（例如使用'-r100'参数）。
print(FigureHandle, Filename, '-dpng', '-r100');
2048x1536px 的文件，请将 Width = 2048/100 和 Height 1536/100，因为您使用的是 100dpi 进行保存所以要除以 /100。如果您更改 dpi 值，您也必须将除数更改为相同的值。screen_size = get(0, 'ScreenSize');
f1 = figure(1);
set(f1, 'Position', [0 0 screen_size(3) screen_size(4) ] );
%% maximizeFigure
%
% Maximizes the current figure or creates a new figure. maximizeFigure() simply maximizes the
% current or a specific figure
% |h = maximizeFigure();| can be directly used instead of |h = figure();|
%
% *Examples*
%
% * |maximizeFigure(); % maximizes the current figure or creates a new figure|
% * |maximizeFigure('all'); % maximizes all opened figures|
% * |maximizeFigure(hf); % maximizes the figure with the handle hf|
% * |maximizeFigure('new', 'Name', 'My newly created figure', 'Color', [.3 .3 .3]);|
% * |hf = maximizeFigure(...); % returns the (i.e. new) figure handle as an output|

这是最短的形式

set 命令来更改图形的 MenuBar 和 Toolbar 属性。由于它适用于更旧和更新版本的 Matlab，所以 set 命令更加灵活多用。fig = figure(1);
set(fig, 'MenuBar', 'none');
set(fig, 'ToolBar', 'none');
set将您的图形设置为全屏。set(fig, 'Position', get(0,'Screensize'));
