How do I decrease the margins around the subplots in my figure in MATLAB?

I would like to decrease the white space around my plots because when I copy the figure to a Word document, the margins around the axes reduces the size of the plot and I often have to crop this space out in order to increase the plot's size.

From R2019b, you can minimize the space around the plots by using tiledlayout function.
For details, please see the following documentation.
- Saving and Copying Plots with Minimal White Space
If you use R2019a and earlier releases, please refer the following information:
The ability to set margins for subplots in a figure is not currently available in MATLAB. However, you may refer to the user-contributed functions "subaxis" or "subtightplot" at MATLAB Central that provides this functionality:

I know the question is very old, but it's still very interesting.
A simple way of doing what you want (change margins of subplots) is this:
pos = get(gca, 'Position');
pos(1) = 0.055;
pos(3) = 0.9;
set(gca, 'Position', pos)
to write just after you create each (sub)plot.
This way each plot is resized. 'Position' is the axis property (a 1 x 4 vector) with these fields:
[x y width height]
Obviously, you can change any of the four values to your best choice.

Although ugly, for me it seems to help to multiply the distribution of the subplots for instance by a factor 2:
ax1 = subplot(1,8,[1,2]); .. ax2 = subplot(1,8,[3,4,5,6]); .. %probably not related: ylim([ymin ymax]); .. ax3 = subplot(1,8,[7,8]); linkaxes([ax2,ax1,ax3],'y');
instead of: ax1 = subplot(1,4,1) ax2 = subplot(1,4,[2,3]) ax3 = subplot(1,4,4)
You can use the following code:
ax = gca;
outerpos = ax.OuterPosition;
ti = ax.TightInset;
left = outerpos(1) + ti(1);
bottom = outerpos(2) + ti(2);
ax_width = outerpos(3) - ti(1) - ti(3);
ax_height = outerpos(4) - ti(2) - ti(4);
ax.Position = [left bottom ax_width ax_height];
I found it here: https://uk.mathworks.com/help/matlab/creating_plots/save-figure-with-minimal-white-space.html. I think it should only work for MATLAB R2019b or later versions, but it works for me with version R2018b.
