Starting in R2019b, you can use the tiledlayout and nexttile functions to create a configurable tiling of plots. The configuration options include: 
  • Control over the spacing between the plots and around the edges of the layout 
  • An option for a shared title at the top of the layout 
  • Options for shared x- and y-axis labels 
  • An option to control whether the tiling has a fixed size or variable size that can reflow 
An example of 'tiledlayout' used to create a 2x2 group of subplots is written below:
figure()
tcl = tiledlayout(2,2);
nexttile
title('First Subplot')
nexttile
title('Second Subplot')
nexttile
title('Third Subplot')
nexttile
title('Fourth Subplot')
title(tcl,'Subplot Grid Title')
For more information, see Combine Multiple Plots
 
Starting in R2018b, you can use the 'sgtitle' function to add a title to a group of subplots. For example: 
subplot(2,2,1) 
title('First Subplot') 
subplot(2,2,2) 
title('Second Subplot') 
subplot(2,2,3) 
title('Third Subplot') 
subplot(2,2,4) 
title('Fourth Subplot') 
sgtitle('Subplot Grid Title') 
For more information on the 'sgtitle' function, see https://www.mathworks.com/help/matlab/ref/sgtitle.html.
In previous releases (before R2018b), you can create the appearance of a super title by creating the subplots in a panel and adding a title to the panel. For more information,

suptitle() is part of the Bioinformatics toolbox.

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

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')

Starting in R2018b, you can use sgtitle to add a title to subplot grids:

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.

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.

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');
