This one threw me for a while too.

First thing, the gksm2ps output is not strictly EPS compliant. There is a line
in the postscript that causes problems when trying to include the graphic in a
LaTeX file. The best way to exclude the problematic line is to use grep. For

grep -v initmatrix FILENAME.ps > NEWFILENAME.ps

This will exclude a line that contains the command `initmatrix' from the
postscript file. Now you can include the EPS file in a LaTeX document. (You
could also just edit the .ps file, search for initmatrix and delete the whole

The best way I have found for including postscript files in LaTex is via the
pstricks macros written by Timothy Van Zandt. This is freeware, and should be
available at CTAN archives, if I remember correctly. This gives you a lot more
flexibility than anything else I have tried. Here is a brief example:

In the document declaration include epsf and pstricks:

\documentstyle[<your other definitions>,epsf,pstricks]{article}

Then to include a graphic:

%  \psgrid

The pspicture declares the positioning of a graphics "space" in the document,
psgrid turns on a useful underlying grid, that helps with positioning and
sizing, epsfxsize is the usual scaling command,
rput allows positioning and rotation of the graphic, epsfbox include the eps

It's pretty quick and dirty. Plus there are alot of other nice tricks in the
pstricks macros that I find useful.

Hope this helps! Mark
