% DESCRIPTION
% ===========
%
% From eof_arpege\_\ *simulation*\ _  \ *period1*\ -\ *period2*\ d.mat,
% ``time_serie_eof_df`` compute ++.
%
% ``time_serie_eof_df`` plot ++.
%
% ``time_serie_eof_df`` save eof[12]_arpege_\ *simulation*\ _  \ *period1*\ -\ *period2*\ d.txt.
%
% 2 Postscript files
% time_serie_arpege\_\ *simulation*\ _ \ *period1*\ -\ *period2*\ d_part[12].eps are
% written.
%
% EXAMPLES
% ========
%
% Following line read ``eof_arpege_TrNQIVIV_10-30d.mat``,
% compute ++,
% plot ++,
% write ``eof[12]_arpege_TrNQIVIV_10-30d`` and
% write ``time_serie_arpege_TrNQIVIV_10-30d_part[12].eps``
% ::
%
% >> time_serie_eof_df('arpege','TrNQIVIV',10,30)

%
% - fplod 2009-02-02T10:01:21Z aedon.locean-ipsl.upmc.fr (Darwin)
%
%   * created from time_serie_afr_1030.m to replace it as well as
%     time_serie_afr_30100.m, time_serie_as_1030.m, time_serie_as_30100.m,
%     time_serie_ctl_1030.m, time_serie_ctl_30100.m, time_serie_tr_1030.m and
%     time_serie_tr_30100.m
%
%     Days will be now written ``period1``\-``period2d`` (ex: 10-30d) in filenames.
%
%     Dataset ``arpege`` will be forced in output file names.
%
%     Simulation name will be add to  output file names (see parameters).
%
%     Postscript files names will be suffixe by partx instead of letter.
