% DESCRIPTION
% ===========
%
% plot ++ from file :file:`eof_10-30d_jjas.mat`
%
% EXAMPLES
% ========
%
% Following line read :file:`eof_10-30d_jjas.mat`, plot ++and produce a Postcript file
% :file:`resultats_eof_jjas_2006_10-30d.eps`
% produce also :file:`carte_eofx_mode_sahel_10-30d.dat` and 
% :file:`carte_eofx_mode_sahel_10-30d.ctl` (GRADS files) and 
% :file:`vecteurs_eof_10-30d.txt`::
%
% >> carte_eof234_jjas_df(10,30);

%
% TODO
% ====
%
% improve description
%
% improve file pb
%
% use return function
%
% change filename of Postscript file because same as in carte_eof_ER_jjas_df.m
%
% directory for sauvegrads files
%
% control of sauvegrads call
%
% why ``-carte`` in contourf and sauvegrads instead of ``carte`` ?

% - fplod 2009-02-11T16:27:34Z aedon.locean-ipsl.upmc.fr (Darwin)
%
%   * add try/catch on opening file for reading
%
% - fplod 2009-02-10T14:28:00Z aedon.locean-ipsl.upmc.fr (Darwin)
%
%   * replace ndmin by period1 and ndmax by period2
%
% - fplod 2009-01-27T14:49:51Z aedon.locean-ipsl.upmc.fr (Darwin)
%
%   * created from carte_eof234_jjas_1025.m and carte_eof234_jjas_1030.m
%     to replace both.
%
%     Days will be now written ``period1``\-``period2d`` (ex: 10-30d) in filenames.
%
%   *  add sauvegrads on first EOF for homogenity
