% DESCRIPTION
% ===========
%
% From eof\_\ *period1*\ -\ *period2*\ d_jjas.mat, 
% ``time_serie_jjas_df`` compute ++.
%
% ``time_serie_jjas_df`` plot ++.
%
% ``time_serie_jjas_df`` save eof[123]\ *period1*\ -\ *period2*\ d.txt.
% 
% 2 Postscript files
% time_serie_jjas\_\ *period1*\ -\ *period2*\ d_part[12].eps are
% written.
%
% EXAMPLES
% ========
%
% Following line read ``eof_10-30d_jjas.mat``, 
% compute ++,
% plot ++, 
% write ``eof[123]_10-30d.txt`` and
% write ``time_serie_jjas_eof1_10-30d_part[12].eps``
% ::
%
% >> time_serie_jjas_df(10,30);

% improve description
%
% improve file pb
%
% use return function
%
% nb of figure depends on number of years to be plot : so figure(3) contains 
% something only if nb years > 23 (or so), so Postscript file of figure(3) 
% shoul not be saved if  nb years is less than 23 !
