I'm exporting an image in Matlab using the eps format, but it smooths the image. Matlab does not blur the image using other formats such as png. I would like to know how to export a non-blurry image with eps format. Here is the resulting image using png: enter image description here

And here is the resulting image using eps: enter image description here

not sure why it works but you can try doing the following:

This page helped me a lot: http://tech.mof-mof.co.jp/blog/machine-learning-octave.html (written in Japanese, please use google translate for it)

And this is also helpful: Octave-Gnuplot-AquaTerm error: set terminal aqua enhanced title "Figure 1"...unknown terminal type"

I also answered at https://www.coursera.org/learn/machine-learning/discussions/weeks/2/threads/Dh-aRfqSEeaHSQ6l4xnh6g.

I reinstalled gnuplot like this:

$ brew cask install xquartz
$ brew cask install aquaterm
$ brew uninstall gnuplot
$ brew install gnuplot --with-aquaterm --with-x11 --with-qt  # you can show other options by `$ brew options gnuplot`

You may edit ~/.octaverc like this:

setenv("GNUTERM", "qt")

and in octave window, after typing "system gnuplot", then

set pm3d interpolate 2, 2

After saving the file, open octave-cli.app, and type

imagesc(magic(3)), colorbar

I got this.
