Force matlab to save .eps without rasterizing vector graphics

forceVectorGraphics.m

plot3(X,Y,Z) %Plot your awesome plot

set(gcf,'renderer','Painters') % 1) Change the renderer of the figure before you draw your figure or before you export. You can use the following command>>
% Change the renderer used by the PRINT command. By default it uses the same renderer that the figure uses, so you would have to type the following command to over-ride this:
print -depsc -tiff -r300 -painters <filename>.eps %  modify <filename> to your hearts desire
% modular filename way:
print('-depsc','-tiff','-r300', '-painters',[filename,'.eps'])

I would recommend to use 'ContentType','vector' of https://de.mathworks.com/help/matlab/ref/exportgraphics.html

%EPS
exportgraphics(gcf,'myVectorFile.eps','BackgroundColor','none','ContentType','vector')
%PDF
exportgraphics(gcf,'myVectorFile.pdf','BackgroundColor','none','ContentType','vector')

an example:

clear
close all
warning('off','MATLAB:print:ContentTypeImageSuggested')%turn of irrelevant Warning (Vector is not slower than Raster)

gcf=figure(314159265);
sphere %plot3(X,Y,Z) %Plot your awesome plot
daspect([1 1 1])%assure that it is not distored

%% Uggly RasterOutput
disp('Rasterouptut')
print('-depsc','-tiff','-r300','UgglyRaster.eps')%uggly: Rastergraphics
print('-dpdf','UgglyRaster.pdf')%uggly: Rastergraphics

%% Vector Output1 (no border for PDF, and optional transparent background)
disp('exportgraphics')%for R2020a or newer https://de.mathworks.com/help/matlab/ref/exportgraphics.html
exportgraphics(gcf,'myVectorFile1.eps','BackgroundColor','none','ContentType','vector')
exportgraphics(gcf,'myVectorFile1.pdf','BackgroundColor','none','ContentType','vector')

%% Vector Output2
disp('-vector')%In R2022a -painters got replaced by -vector

print('-dpdf','-r300', '-painters','myVectorFile2.pdf')%uggly: has large white borders
