startdate : enddate
startdate : increment : enddate
startdate
[ numeric ] - IRIS serial date number representing the startdate.
enddate
[ numeric ] - IRIS serial date number representing the enddate; startdate
and enddate
must be the same frequency.
increment
[ numeric ] - Number of periods (specific to each frequency) between the dates in the date vector.
You can use the colon operator to create continuous date ranges because the IRIS serial date numbers are designed so that whatever the frequency two consecutive dates are represented by numbers that differ exactly by one.
