Henrik: That didn't work for me. Thank you, though.
Doug: To reproduce the problem, do the following:
I would attach the resulting eps file, but the MathWorks forum does not allow me to upload a *.eps file.
In any case, when I run that code and open the eps file in Preview (Mac OS X built-in viewer), it shows the figure at the bottom left corner of a 8.5 x 11" standard page. There is needless white space around the figure. Running this same code in Matlab 2012a doesn't do this.
