matlab - Killing a script in the middle of a parfor: how to close open files?

Question

When I interrupt a script in the middle of a parfor, some files are still opened by Matlab (e.g. I cannot delete them). I usually call flcose('all') to close all open files but it doesn't seem work in this case. What should I do?

Answer 1

那是因为parfor创建了一堆拥有自己文件句柄的 Matlab 从站。两个主要的解决方案是：

parfor i=1:12 % 12 or some number over your number of workers
   fclose('all')
end

或者简单地使用matlabpool close或 GUI（左下角）关闭并行池：

请注意，您可以使用Process Explorer来查找在 Windows 中打开文件的进程：
