在 MATLAB Online 中打开

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.
