I wish add a few of white space around my .eps figure to avoid that overleaf (compiler: pdfLaTex) cuts it on one side as you can see in the following image (zooming):

Original image:

The code that I use to produce the image is:

figure(2)
plot(...
    vTime, convangvel(p(vTime),'rad/s','deg/s'),'-', ...
    vTime, convangvel(q(vTime),'rad/s','deg/s'),'-', ...
    vTime, convangvel(r(vTime),'rad/s','deg/s'),'-','LineWidth',0.7...
    );
axis([0 t_fin -2.5 2.5]);
grid minor;
xlabel('{\it t} (s)'); ylabel('(deg/s)');
legend({'{\it p(t)}','{\it q(t)}','{\it r(t)}'},'location','northeast');
set(gcf,'position',[400, 200, 560, 315],'PaperOrientation', 'landscape'); 
print('-depsc2','-r600',strcat('es5_vel_ang','.eps'));

Can you suggest me how to modify thi code correctly in order to avoid that issue when I import the figure in overleaf?

在 MATLAB Online 中打开

A simple plot as an example:

figure()
plot([1 2], [1 2]);
set(gcf,'position',[400, 200, 560, 315],'PaperOrientation', 'landscape'); 

Using print like you did gives the tight bounding box which I dislike for the same reasons for my LaTeX documents:

%% print without rim
print('-depsc2','-r600',strcat('test_tight','.eps'));

(I'm showing screen shots from IrfanView to clarify the bounding boxes)

A simple but unflexible way is to use the '-loose' option of the print command. Like in

%% try print with -loose option
print('-depsc2','-r600',strcat('test_loose','.eps'),'-loose');

which will give you relatively wide additional margins:

A more complex way is to use the print2eps function from export_fig on FileExchange, https://uk.mathworks.com/matlabcentral/fileexchange/23629-export_fig :

%% try print2eps from export_fig on FileExchange
print2eps('test_rim2.eps',gcf,struct('bb_padding',0.01,'regexprep',[],'crop',1));

You need to set 'regexprep' to empty [] to avoid a run time error, and set 'crop' to 1 to enable changing the bounding box at all. Then, 'bb_padding' with 0.01 will add just a little rim, so your figure can almost fill \textwidth in LaTeX:
