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: harvest.m
    path of file: ./repos/bspm/thirdparty/spm12/matlabbatch/@cfg_repeat
    
    the code of the file until where you have to start completion: function [tag, val, typ, dep, chk, cj] = harvest(item, cj, dflag, rflag)

% function [tag, val, typ, dep, chk, cj] = harvest(item, cj, dflag, rflag)
% Harvest a cfg_repeat object.
% Input arguments:
% item  - item to be harvested
% cj    - configuration tree (passed unmodified)
% dflag - if true, harvest defaults tree, otherwise filled tree
% rflag - if true, resolve dependencies in leaf nodes
% O
    
function and its
%       childrens check functions. A job is ready to run if all
%       dependencies are resolved and chk status is true.
%
% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
% for a general overview.
