% This example shows how to include a PostScript figure into
% a LATEX document.  This assumes that you are using the public
% domain TEX on notiid or matrix, not ArborTeX.
% It is preferable that your figure be in an encapsulated
% PostScript form (usually .eps or .epsi).  Your figure software may
% do this for you, but you can also check out the command 'pe2epsi'
% to convert a PS file to EPS format.
% You must include the epsf macro set in \documentstyle[]
% This example assumes that f31.ps is in the same directory as your
% tex file.
% -----------------------------------------------------------------
%
% The next command specifies that the PS figure is to be scaled to
% give a picture 3 inches horizontally.
% check /usr/local/lib/texmf/tex/dvips/epsf.tex for other options!
