function laprint(figno,filename,varargin)

%LAPRINT prints a figure for inclusion in LaTeX documents.

%  LaPrint creates an eps-file and a tex-file. The tex-file contains

%  the annotation of the figure such as titles, labels and texts. The

%  eps-file contains the non-text part of the figure as well as the 

%  position of the text-objects. The packages 'graphicx' (or 'epsfig')

%  and 'psfrag' (and possibly ''color'') are required for the LaTeX 

%  run. A postscript driver like 'dvips' is required for printing. 

%

%  Usage:   >> laprint

%

%  This opens a graphical user interface window, to control the

%  various settings. It includes a help facility. Just try it.

%

%  As an alternative to the GUI you can call laprint from the command

%  line with various extra input arguments. These arguments are 

%  explained in the help window of the GUI, which can be also be 

%  opened using the command

%      >> laprint helpwindow

%

%  There is an Users Guide available at

%      http://www.uni-kassel.de/fb16/rat/matlab/laprint/laprintdoc.ps
