Between submitting a manuscript and receiving its reviews, I upgraded to Matlab 2015a. I am now updating the figures in response to the reviews. The plots are information-rich, some containing a filled contour plot behind a quiver plot. The old version of Matlab handled the graphics beautifully, with average file size < 1 MB. I am using identical scripts to plot, but now the average file size is > 30 MB, making editing and uploading untenable. The final print command is:
print -painters -depsc filename.eps
I've seen that others have posted similar questions, but cannot find a work-around that solves it.
