I would like to place a title over a group of subplots. How can I do this?

As of MATLAB R2018b, the sgtitle function will add a title over a group of subplots.
For earlier releases, check out the user-contributed mtit File Exchange submission for this functionality. If you have any questions, consult the author.
function gives you a similar functionality.

But good god just fix it then. Plotting in matlab is is joke (a sad one), always forced to resort to user provided workarounds...

There’s a new feature in 2018b which makes it possible

Starting in R2019b, you can also use tiledlayout and nexttile instead of subplot, which has shared titles and labels. You can use the title, xlabel, and ylabel commands directly with tiledlayouts:
Alternatively, starting in R2018b, the sgtitle function will add a title over a group of subplots.
tl = tiledlayout(3,3);
for i = 1:9
nexttile(tl)
plot(rand(5,1));
end
title(tl,'Layout Title');
xlabel(tl,'Layout XLabel');
ylabel(tl,'Layout YLabel');

Suptitle does the job
x=1:0.01:10;
subplot(2,2,1); plot(sin(x))
subplot(2,2,2); plot(cos(x))
subplot(2,2,3); plot(cos(x.^2))
subplot(2,2,4); plot(sin(x.^2))
suptitle('I am a super title')

Here's a solution that doesn't require additional functions.
figure;
subplot(2, 1, 1);
plot(nan, nan);
subplot(2, 1, 2);
plot(nan, nan);
currentFigure = gcf;
title(currentFigure.Children(end), 'blah');

A problem with sgtitle (at least on the linux distro) is that it seems to be persistent, meaning once you put an sgtitle into the figure you cannot get rid of it. How can one clear an sgtitle?
Not being able to clear it complicates making AVI videos using subplot.
I imagine there is a way to completetely delete the sgtitle using a handle to it (before writing the next one), but I haven't figured out yet how to do so. Can anyone provide guidance?
Thanks! Jeff

figure;

plot(nan, nan);
subplot(1, 2, 2);
plot(nan, nan);
ha = axes('Position',[0 0 1 1],'Xlim',[0 1],'Ylim',[0 1],'Box','off','Visible','off','Units','normalized', 'clipping' , 'off');
text(0.5, 0.98,'Title')

how can i display images in MATLAB like this.
Walter Roberson 2019 年 5 月 11 日
There are multiple possibilities. The ones I can think of off-hand include:
• create an axes for each of the images, and an axes for each of the titles above and each of the titles to the side. Using subplot() for this purpose is not great, as you do not want the axes to all be the same size. Each axes could been panned, scrolled, zoomed, or data cursored individiually.
• create the top left axes with room for title and ylabel and an image. Create 3 axes below that with room for ylabel and an image. Create top right axes with room for title and image. Create three axes below that with room for an image. Using subplot() for this purpose is not great, as you do not want the axes to all be the same size. Each axes could been panned, scrolled, zoomed, or data cursored individiually.
• create a 4 x 2 array of axes the same size, all large enough to accomodate title and ylabel. Then carefully "tuck" the axes in so only the wanted parts show. Using subplot() for this might not be bad, but you will need to move the axes carefully. Each axes could been panned, scrolled, zoomed, or data cursored individiually.
• Use montage or similar to create a 4 x 2 image array and display it in an axes that you put appropriate text labels on. It would not be possible to scroll or pan or zoom the images individually, and you would need extra work to data cursor them individually. On the other hand, a single movable graphics cursor covering multiple images would become easier than in the other approaches mentioned above

With respect, this is not a helpful comment, as it's apparently not true. It is possible, just not with built-in core Matlab functionality. Most people will hopefully continue reading the thread, and learn about the workarounds. Still, it's not an encouraging or precise statement to begin the group discussion, IMHO.

There is a function suptitle which may does our work. It puts perfectly the title over all subplots.
Cris LaPierre 2018 年 10 月 25 日
FYI: suptitle is only available to those who have the Bioinformatics toolbox, and then it was included in a demo file and is not an actual MathWorks maintained function.
However, as Paul Huxel points out, there is now (r2018b) a function in base MATLAB for this. It is called sgtitle.

Thanks! This works great. I set did >set(h,'Position',[.5 1.05 .5]) to get place the supertitle above the titles of my subplots.

A great big thank you to the writer of mtit! That worked great for me, being someone who is between 2018 and the version I originally wrote my code in where my title for the subplot was centered without having to do anything extra.
