麻烦大神帮忙看看这个错误提醒要怎么修改？非常感谢！

错误使用 Idletime (line 37)
在 'Difference' 的工作进程上引发了 UndefinedFunction 错误。这可能是因为在这些工作进程上无法访问包含 'Difference' 的文件。使用
addAttachedFiles(pool, files) 指定要附加的必要文件。请参阅 'parallel.Pool/addAttachedFiles'的相关文档以获取更多详细信息。

出错 IDLETIME_NEH_PR_LJP (line 7)
parfor qq = 1:120

原因:
未定义与 'double' 类型的输入参数相对应的函数 'Difference'。

代码如下：

function [OUTPUT,OUTPUTTIME]=IDLETIME_NEH_PR_LJP
% Take idle time as objective when insert new job to partial sequence
% martix including job operation time, n jobs and m machines
%

%% read data from excel
parfor qq = 1:120

在parfor前用addAttachedFiles函数添加一下Difference函数试试。
