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: initialise.m
    path of file: ./repos/ExploreASL/External/SPMmodified/matlabbatch/@cfg_repeat
    
    the code of the file until where you have to start completion: function item = initialise(item, val, dflag)

% function item = initialise(item, val, dflag)
% Initialise a configuration tree with values. If val is a job
% struct/cell, only the parts of the configuration that are present in
% this job will be initialised. If dflag is true, then matching items
% from item.values will be initialised. If dflag is false, matching items
% from item.values will be added to item.val and initialised after
% copying.
% If val has the special value '<DEFAULTS>', the entire configuration
% will be updated with values from .def fields. If a .def field is
% present in a cfg_leaf item, the current default value will be inserted,
% possibly replacing a previously entered (default) value. If dflag is
% true, defaults will only be set in item.values. If dflag is false,
% defaults will be set for both item.val and item.values.
%
% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
% for a general overview.
