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: update_deps.m
    path of file: ./repos/PsPM/src/ext/matlabbatch/@cfg_repeat
    
    the code of the file until where you have to start completion: function item = update_deps(item, varargin)

% function item = update_deps(item, varargin)
% This function will run cfg_dep/update_deps in all leaf (cfg_entry,
% cfg_menu, cfg_files) nodes of a configuration tree and update their
% dependency information (mod_job_ids) if necessary.
%
% This function is identical for all cfg_intree classes.

% This code is part of

% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
