You can form up to six fields from letters and digits separated by any other characters: datenum takes an input string in any of several formats, with 'dd-mmm-yyyy', 'mm/dd/yyyy', or 'dd-mmm-yyyy, hh:mm:ss.ss' most common. The datenum function is important for doing date calculations efficiently. Here are some examples of conversions from one date format to another. Split date number or date string into individual date elements Here are examples of the three date formats used by MATLAB.įunctions that convert between date formats are shown below.Ĭonvert date string to serial date numberĬonvert serial date number to date string Dates can also be converted to date vectors. MATLAB provides functions that convert date strings to serial date numbers, and vice versa. If you are using functions that handle large numbers of dates or doing extensive calculations with dates, you will get better performance if you use date numbers.ĭate vectors are an internal format for some MATLAB functions you do not typically use them in calculations. If you are dealing with a few dates at the MATLAB command-line level, date strings are more convenient. So the string '1, 6:00 pm' in MATLAB is date number 729284.75.Īll functions that require dates accept either date strings or serial date numbers. MATLAB also uses serial time to represent fractions of days beginning at midnight for example, 6 p.m. In MATLAB, serial date number 1 is January 1, 0000. A serial date represents a calendar date as the number of days that has passed since a fixed base date. MATLAB works internally with serial date numbers (729284). When dealing with dates you typically work with date strings (1).
MATLAB works with three different date formats: date strings, serial date numbers, and date vectors.
