How Can I Increment Dates in Matlab?
A date is stored and manipulated in MATLAB as a string, in a vector, or as a single number. MATLAB provides convenient functions to convert between these formats, and also includes a function to increment a date by the time unit you specify. Use the "addtodate" function to increment a date in MATLAB, nesting the "datenum" function as necessary to convert the date before it's incremented.

Type the following command into MATLAB's Command Window to increment the current date by one month:
addtodate(now,1,'month')
The first argument is the date to increment ("now" returns the current date as a number). The second argument is the number to increment by. The third argument is the unit of time to increment by. The result is returned as a single number. To convert a date number to a readable string, pass it to the "datestr" function.

Use any one of the following keywords as the third argument of the "addtodate" function to increment a date by a specific amount: 'year', 'month', 'day', 'hour', 'minute', 'second', or 'millisecond'.

Use the "datenum" function to convert any MATLAB date to the format required by "addtodate:"
addtodate(datenum('10-Jul-2011'),1,'day')
In this case, a date represented as a string is passed to "datenum" before being passed to "addtodate." Pass any date variable to "datenum" to ensure that "addtodate" will work properly.
