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:
