设置图形大小

我想做的就是让宽度变大，高度变小。我只是做光栅图，但这个问题适用于任何 MATLAB figure。我可以手动调整它的大小使用图形直接当它被创建，但我希望程序吐出在正确的大小开始。

最佳答案

The properties that can be set for a figure is referenced here.

You could then use:

figure_number = 1;
x      = 0;   % Screen position
y      = 0;   % Screen position
width  = 600; % Width of figure
height = 400; % Height of figure (by default in pixels)


figure(figure_number, 'Position', [x y width height]);

 figure (1)
hFig = figure(1);
set(gcf,'PaperPositionMode','auto')
set(hFig, 'Position', [0 0 xwidth ywidth])
plot(x,y)
print -depsc2 correlation.eps;       % for saving in eps, look up options for saving as png or other formats you may need

This saves the figure in the dimensions specified

Write it as a one-liner:

figure('position', [0, 0, 200, 500])  % create new figure with specified size

I managed to get a good result with the following sequence (run Matlab twice at the beginning):

h = gcf; % Current figure handle
set(h,'Resize','off');
set(h,'PaperPositionMode','manual');
set(h,'PaperPosition',[0 0 9 6]);
set(h,'PaperUnits','centimeters');
set(h,'PaperSize',[9 6]); % IEEE columnwidth = 9cm
set(h,'Position',[0 0 9 6]);
% xpos, ypos must be set
txlabel = text(xpos,ypos,'$$[\mathrm{min}]$$','Interpreter','latex','FontSize',9);


% Dump colored encapsulated PostScript
print('-depsc2','-loose', 'signals');

A different approach.
On the figure() call specify properties or modify the figure handle properties after h = figure().

This creates a full screen figure based on normalized units.
figure('units','normalized','outerposition',[0 0 1 1])

The units property can be adjusted to inches, centimeters, pixels, etc.

See figure documentation.
