在 MATLAB Online 中打开

ph = handles.YourPopup;
lh = handles.YourListbox;
selection_index = ph.Value;
if ~isempty(selection_index)
  user_chosen_folder = ph.String{selection_index};
  dinfo = dir(user_chosen_folder);
  dinfo([dinfo.isfolder]) = [];   %only want file names
  filenames = {dinfo.name};   %names of the files
  lh.String = filenames;      %put the names in the listbox
  drawnow()
end

Why don't you try the code that Walter gave you? If you don't understand a function, try reading the documentation. You asked what a specific variable meant, I explained it. If you don't understand the explanation, please say so, because giving you a code example will not help explaining what that value means.
