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: subsref_job.m
    path of file: ./repos/spm12/matlabbatch/@cfg_branch
    
    the code of the file until where you have to start completion: function varargout = subsref_job(item, subs, c0)

    
function varargout = subsref_job(item, subs, c0)

% function [ritem varargout] = subsref_job(item, subs, c0)
% Treat a subscript reference as a reference in a job structure instead
% of a cfg_item structure. If subs is empty, then the harvested subtree
% beginning at item will be returned. Otherwise, subs(1) should have a
% subscript type of '.' in combination with a tagname from item.val.
% The third argument c0 is a copy of the entire job configuration. This
% is only used to reference depend
