Which function are you using? Are you saving an image or a figure() window?

I use saveas(gcf,'filename.jpg') in my code

If you use print() instead of saveas(), then you can give a resolution by using a '-r' option. For example,
set(gcf,'PaperPositionMode','auto')
print('YourFileName.jpg','-djpeg','-r0') %corrected
which would print at screen resolution.

set(gcf,'PaperPositionMode','auto')
print('YourFileName.jpg','-djpeg','-r0') %note correction compared to my earlier comment
which would print at screen resolution.

Try using exportgraphics().
Save the file as a PNG format file instead of JPEG to avoid lossy compression artifacts.
