How can I save my figure to eps AND keep white margins (from my defined figure and axes position)?

I am producing multiple figures which I then need to vertically align in latex. I set my figure and axes position like this:
% Set figure total dimension
set(gcf,'Units','centimeters')
set(gcf,'Position',[0 0 4.5 5.8])
% Set size and position of axes plotting area within figure dimensions. To
% keep vertical axes aligned for multiple figure keep the horizontal
% position consistent
set(gca,'Units','centimeters')
set(gca, 'Position',[1.5 1.3 2.85 4])
Some of my figures have a ylabel and some don't, which thanks to the above set position does not affect the format of the figure. However when I save my figure to eps using
saveas(gcf,'filename','epsc')
the eps file saves it as the tightest fit, ignoring my set positions. How can I get it to save whilst conserving my set formatting?
I've tried saving to .png but the quality is massively reduced (even when using the package export_fig). Is there a simple solution?
I am on MacOs.

Hi @Zoe,
If we go through the documentation of “Printing and Exporting” property of figure then we can see that we should use “PaperPosition” and “PaperUnits” as properties rather than “Position” and “Units” for the figure object while printing or exporting.
Updating your code as below should give you the desired results:
% Set figure total dimension
set(gcf,'PaperUnits','centimeters')
set(gcf,'PaperPosition',[0 0 4.5 5.8])
You can also go through the following MATLAB Answer and MathWorks documentation for more information on “Printing and Exporting” property of figure:

Hi @Jatin Singh
Thank you so so much!! I have been stuck on this for days.
Also in case anyone else has a similar problem, I found that then putting my axes units into normalised allowed me to create the figure I wanted, for some reason my paperunits in centimetres did not match well with axes units in centimetres.
I can't thank you enough. I now actually have hope that my thesis will look nice!!

Hi again @Jatin Singh, it appears I am still struggling with this after all... As soon as I remove a label, my axes no longer align the way I've prescribed in the axes environment which messes up the alignement in my latex document... do you have any suggestions for this?
