%! The frequency and initial date can be specified with variables FREQ__ and INIT__ in the matlab/octave script. FREQ__ must be a scalar integer and INIT__ a string like '1938M11', '1945Q3', '1973W3' or '2009'. If these variables are not specified default values for freq and init are 1 and dynDate(1).
