Convert a date specified by year, month and day values to a serial date number. n = datenum(2001,12,19) n = 731204 Input Arguments collapse all Dates and times, specified as an array ofdatetimeordurationvalues. Thedatenumfunction does not account for time zone information intand does not ...
To convert duration arrays to numeric arrays, use the years, days, hours, minutes, seconds, and milliseconds functions. When the input argument is a duration array, these functions return numeric arrays that represent the number of years, days, hours, minutes, seconds, or milliseconds that were...
