I have converted date to serial number:
A= 10-Jan-2000
D = datenum(A)
D = 730495
And after doing some operation, I want to change (D) it back to the date format. But could not.
Is there any function to convert serial number to date format?

Depending what operations you need to perform, you may be able to keep your data as a datetime array without converting it to serial date numbers. But if you do, datetime can convert serial date numbers into a datetime array.
>> dt = datetime('now')
dt =
datetime
30-Sep-2020 09:48:21
>> sdn = datenum(dt)
sdn =
7.3806e+05
>> dt2 = datetime(sdn, 'ConvertFrom', 'datenum')
dt2 =
datetime
30-Sep-2020 09:48:21
As an example of some operations defined on datetime arrays, you can perform date and time arithmetic using datetime and duration arrays.
>> dt3 = dt + hours(1) + minutes(2) + seconds(3) % datetime + duration = datetime
dt3 =
datetime
30-Sep-2020 10:50:24
>> du = dt3 - dt2 % datetime - datetime = duration
du =
duration
01:02:03

A = '10-Jan-2000';
D = datenum(A);
D = D + 10;
B = datestr(D);
Result
>> B
B =
'20-Jan-2000'
