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: fillvals.m
    path of file: ./repos/bspm/thirdparty/spm12/matlabbatch/@cfg_item
    
    the code of the file until where you have to start completion: function [item, inputs] = fillvals(item, inputs, infcn)

% function [item, inputs] = fillvals(item, inputs, infcn)
% If ~all_set_item, try to set item.val{1} to inputs{1}. Validity checks
% are performed through subsasgn. If inputs{1} is not suitable for this
% item, it is discarded. If infcn is a function handle,
% [val sts] = infcn(item) 
% will be called to obtain a value for this item. This call will be
% repeated until either val can be assigned to item or sts is true. val
% should be a cell array with 1 item and val{1} the value that is to be
% assigned to item.val{1}.
% This function is suitable for all cfg_leaf items.
