Published LaTex images too small

When I use the publish command, even on the example code included in the matlab documentation, the LaTex image files that are published turn out to be 2 pixels by 1 pixel

You can publish file with images of size you want in Latex using "Publish" button with custom setting i.e. image pixels setting.

Unfortunately, that setting is not affecting the equations, just the figures. Any other thoughts?
