java - Matlab 错误 : Caught "std::exception" Exception message is:

Question

我可以连接到一台服务器，在我的本地 ubuntu 12.10 电脑中有两个版本的 matlab Matlab_R2013a、Matlab_R2012a 和另一个版本的 Matlab_R2012b。在过去的几周里，我一直面临着一个问题。有时我可以在我的电脑上运行代码，但如果它需要很长时间，或者如果我尝试运行类似的代码几次，我会收到错误消息并且 Matlab 不再工作。服务器中的 Matlabs 也发生了同样的事情。我必须重新启动，然后我可以再次运行 matlab 一小段时间，但在那之后我又一次又一次地面临同样的问题。

Matlab 显示的错误是

我删除了本地 .matlab 文件夹。但在那之后我也再次面临同样的问题。

请帮我在 MATLAB 中解决这个问题。提前谢谢你。

回答问题基本上是打开的文件太多。

Answer 1

我遇到过类似的问题，正如 Petesh 所说，这是一个文件句柄问题 - MATLAB 一次只能打开这么多文件。快速修复是在 MATLAB 命令窗口中执行 fclose all。要检查您打开了多少个文件句柄，请使用 fopen('all') 它将显示 Activity 句柄列表。 (我的 MATLAB 2013a 版本在 512 个打开文件时已满)。

从它生成的所有错误行中挑选出的关键错误消息是

(Too many open files)

更好的解决方案是确保所有脚本在打开文件后关闭文件，特别是如果您每次都在循环中打开文件。
