computing number of days between a matrix of dates

Dear All, I have a long file of "dates of occurrences" of events, which are expressed in numbers as Year, Month, Day, Hour, Minutes (e.g. May 23, 2015 at 09:15 is the vector [2015 05 23 09 15]). I want to compute for each event, the distance in days from the starting date (e.g. [2000 01 01 00 00]). Could anyone provide some advice, as to loop the computation? Best regards, Rosanna

Put all dates in datetime format

T = datetime(Tvec)

then

Tdiff = T - T(1)

will output a duration vector
