New Answer:
Hm, I couldn't find an option to change that resolution. Looked at their Matlab codes publish.m which brought me to their code evalmxdom code that draw the images at fairly low resolution...
%publish.m Line 189-192, draws your code figure at low resolution
% Evaluate each cell, snap the output, and store the results.
if options.evalCode
dom = evalmxdom(file,dom,cellBoundaries,prefix,imageDir,outputDir,options);
end
Here's a workaround to increase the figure resolution before publishing. Maybe someone else know of a better way, or has their own code for publishing high-res codes+figures. Maybe MathWorks should add a feature to increase figure resolution to vector graphics. Anyways, here's the workaround:
t = linspace(0,1);
plot(t, exp(-t));
title('This title is blurry')
xlabel('This label is also blurry')
ylabel('The whole picture is slighty pixelated')
%Increase your figure pixel resolution and font sizes
Gx = gcf;
Gx.Position(3:4) = Gx.Position(3:4)*5;
Ax = gca;
Ax.FontSize = Ax.FontSize *3;
then you can publish your code
publish('mycode.m', 'pdf')
Old Answer:
Use print instead.
print(gcf, 'temp.pdf', '-dpdf')
Make sure to setup the figure PaperPosition, Position, etc properly
