These are flags to allow you to supress specific MATLAB code analyzer warnings.

Perhaps best, read here:

As MATLAB has evolved over the years, the need for specific warnings has also evolved. So I don't know of a specific hard list of all possible warnings.

You can also look at the MATLAB preferences for the Code Analyzer.

The recommended/default suppression codes do change by version, and most likely get added/removed too, so any list is likely to need to be version-specific.

sir, where can i find the list for specific version of matlab..?

Now i'm using R2020b

You can suppress any of these warning by just adding

%#ok

behind your codeline to show that you are aware of that warning. At least in R2022b this works for me.

1. Type control-shift-f.
2. In the "Find files containing text" field, put %#ok<
3. In the "Include only file type(s):" field, select *.m
4. Select the current folder, or any other folder you want.
5. Check "Include subfolders" checkbox.
6. Click Find

This will find all places in your m-files where the author put lines like that.

If you actually want to know what those symbols mean, then check the other answer(s).
