Dear all..
i have many file with name by modified julian date..i have used matlab progrrming JD2CAL (Converts Julian date to calendar date using algorithm).. It is succesfull but the problem is when day in January , November and December..For example 1112007.txt represent for 11/1/2007 but problem for file date 1/11/2007 ..it also will rename the file with 1112007.txt..So, the data for this two date will mix together..how i can solve it?

What if use notation like DS_MM_YYYR.txt (for eg. 01_11_2007.txt) ...?

Either use 2 digits for the day and the month, or add a separator.
sprintf('%.2d%.2d%.4d', 1, 1, 2007)
sprintf('%d_%d_%d', 1, 1, 2007)
I'd prefer this, because the alphabetical order equals the temporal order:
sprintf('%.4d%.2d%.2d', year, month, day)

file=datestr(datenum(date),'dd/mm/yyyy')
file([3,6])=[]
file=[file '.txt']

The jd2cal function returns [yr,mn,dy]. It is not the source of the ambiguity.
