Komal - where is odd_flag used in your above code example? Unless you are referring back to https://www.mathworks.com/matlabcentral/answers/383455-need-to-insert-following where the attached m code has a variable named odd_flag which is never used. It is probably safe to remove this unused variable...

odd_flag = 1
assigns the value 1 to the variable odd_flag.
What it means is probably nothing, since it is apparently just an unused variable. Odds are whoever wrote that code used a variable called odd_flag before, but then changed to code to no longer use it, and forgot to delete that line.
You need to understand that you can name a variable virtually ANYTHING you want. There is nothing special about that choice of name. And if it is unused, then it does noting at all, except waste a few CPU cycles to create it.
"also what does ii means"
Very basic concepts like this are explained very well in the introductory tutorials, which are highly recommended for all beginners:
