I have 10 .txt files. In each of these files I have a column of datetime and another column for data. I want to generate a sequence of datetime for the next 500 months for eahc file

file 1: start date: 05-2010 ; end date: 10-2017

file 2: start date: 07-2006 ; end date: 12-2016

(i want dates for the next 500 months to be added below in this same column; in each file)

There's not a lot to go on here. Presumably you will want to read in a file, do somethign in MATLAB, and then write out another file. readtable and writetable are probably the way to go, and the "roll-over" behavior built into datetime may be helpful:

>> datetime(2010,5,1) + calmonths(0:100:500)
ans = 
  1×6 datetime array
   01-May-2010   01-Sep-2018   01-Jan-2027   01-May-2035   01-Sep-2043   01-Jan-2052
