You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: treepart.m
    path of file: ./repos/bspm/thirdparty/spm12/matlabbatch/@cfg_repeat
    
    the code of the file until where you have to start completion: function tname = treepart(item, dflag)

% function tname = treepart(item, dflag)
% tree part to search - for cfg_repeat/cfg_choice this is val for filled
% cfg_items and values for default cfg_items.
%
% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
% for a general overview.
