EPS looks pixelated when exporting figure

I'm trying to export an eps from matlab but it keeps appearing pixelated on the resulting PDF. I'm using:

print -despc my plot.eps

The result in my latex document looks like:

Is there anyway to stop this? As when I load it in the figure window it renders properly and not pixelated.

Do you use the OpenGL renderer in Matlab? If so, try Painters:

set(gcf, 'Renderer', 'Painters');

This is required to get vector graphics in the EPS exort.

If this does not work, export a PNG: Even with pixels the output is clean.
