fclose() - How do I close all open files but one?

I'd like to close all my open files but one, is there a simple way to do it? Simpler than deleting them one by one?

It's possible for variables with:

clearvars -except variable_needed

But unsurprisingly the following does not work:

fclose all -except fileID

Thanks,

Currently, there is no way to close all open files, except one.

There is no direct way. You can

arrayfun(@fclose, setdiff(fopen('all'), fileID));

provided the fileID is given as numeric.
