How to print a figure as a PDF, that has the same size of my figure (or, how to resize the PDF according to my figure dimensions)?

How to print a figure as a PDF, that has the same size of my figure (or, how to resize the PDF according to my figure dimensions)?

In other words, how can I get rid of the upper and lower white margins in the following printed PDF?

(here following I tried to use the method/solution proposed by Sergi Tarroc on 17 Jun 2021)

% create a figure with "subtightplot"
subplot = @(m,n,p) subtightplot (m, n, p, [0.001 0], [0.01 0.01], [0.01 0.01]);
fig = figure('position',[700 100 700 1200],'Color',[1 1 1])
hold on
for i = 1 : 6
    subplot(2,3,i); 
end
hold off

% print the figure as PDF
fig.Units = 'centimeters';          % set figure units to cm
fig.PaperUnits = 'centimeters';     % set pdf printing paper units to cm
fig.PaperSize = fig.Position(3:4);  % assign to the pdf printing paper the size of the figure
path = ( '/Users/Donald/.../' );    % where to print my figure
print (fig(:), '-dpdf','-loose','-opengl','-r600', [path, 'fig'] ) 

This is the resulting PDF, where you can clearly see the upper and lower white margins that I would like to get rid of:

Hi, anyone who can help in this regard? :-)

doesn't this have basically the same solution of what you already asked here? Crop white margins in a PDF file - MATLAB Answers - MATLAB Central (mathworks.com)

Thanks a lot! Yes, that solution works! Sorry for asking something similar to my old post - Maybe I can delete this question (if Matlab moderators/staff thinks it is better)

Solved, thanks to the @Luca Ferro's comment (Yes, similar to my old post - and sorry for asking something similar, I did not realise I could use the same solution, my fault)...Many thanks @Luca Ferro!!

Just the exportgraphics function solves my issue:

% Solution:
% create a figure with "subtightplot"
subplot = @(m,n,p) subtightplot (m, n, p, [0.001 0], [0.01 0.01], [0.01 0.01]);
fig = figure('position',[700 100 700 1200],'Color',[1 1 1])
hold on
for i = 1 : 6
    subplot(2,3,i); 
end
hold off
% print the figure as PDF
path = ( '/Users/Donald/.../' );    % where to print my figure
exportgraphics(fig, fullfile(path, 'fig.pdf'),'ContentType','vector') % this solves my issue

And this is the resulting PDF, without the upper and lower white margins:

At this point, I do not know if the following commands that I have used (by following the method/solution proposed by Sergi Tarroc on 17 Jun 2021) are really necessary, maybe no, or at least I do not see differences:

fig.Units = 'centimeters';          % set figure units to cm
fig.PaperUnits = 'centimeters';     % set pdf printing paper units to cm
fig.PaperSize = fig.Position(3:4);  % assign to the pdf printing paper the size of the figure
