How to calculate series of values by specifying starting time using datenum????????

Hello,

kindly help to solve this issue

I just to want to find the serialdatenumber by specifying the start time and end time using datenum!!!!

%%%%%my code%%%%

starttime = datenum(2018,03,23,10,00,00)

endtime = datenum(2018,03,23,10,10,00)

tme = starttime:endtime

I just need to know how to calculate serialdatenumber for minutes,seconds,milliseconds from 10:00:00 to 10:10:00

starttime = datenum(2018,03,23,10,00,00)
endtime = datenum(2018,03,23,10,10,00)
ms = 1/(24*60*60*1000);
tme = starttime:ms:endtime;

This will be 60001 elements long.

You need to specify a step size.

But you'll likely be much happier using datetimes:

>> starttime = datetime(2018,03,23,10,00,00)

starttime = 
  datetime
   23-Mar-2018 10:00:00
>> endtime = datetime(2018,03,23,10,10,00)
endtime = 
  datetime
   23-Mar-2018 10:10:00
>> starttime:minutes(2.5):endtime
ans = 
  1×5 datetime array
   23-Mar-2018 10:00:00   23-Mar-2018 10:02:30   23-Mar-2018 10:05:00   23-Mar-2018 10:07:30   23-Mar-2018 10:10:00

Thank you Peter!!! But I tried this method also,but It didn't work for me

When I tried this on my command window,what I got is

Starttime =datetime(2018,03,23,10,00,10)

Undefined function 'datetime' for input arguments of type 'double'

Did you mean:

Starttime =date2time(2018,03,23,10,00,00)

For this also it's giving

Error using date2time

Too many input arguments

datetime() was added in R2013b. Which release are you using?

I am working with Matlab R2014a

[Walter Roberson]

I misremembered: datetime() was added in R2014b.
