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: cfg2struct.m
    path of file: ./repos/spm/matlabbatch/@cfg_entry
    
    the code of the file until where you have to start completion: function sitem = cfg2struct(item)

% function sitem = cfg2struct(item)
% Return a struct containing all fields of item plus a field type. This is
% the method suitable for entry classes.
%
% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
% for a general overview.
