Matlab中的错误：捕获“std :: exception”异常消息是：

Question

我可以连接一个服务器，其中有两个版本的matlab Matlab_R2013a，Matlab_R2012a和另一个版本的Matlab_R2012b在我的本地ubuntu 12.10 pc中。在过去的几周里，我一直面临一个问题。有时我可以在我的电脑上运行代码，但是如果花了很长时间，或者如果我尝试运行类似的代码几次，我得到一个错误和Matlab不再有效。 Matlabs也在服务器上发生同样的事情。我必须重新启动，然后再次运行matlab一段时间，但之后我再次面临同样的问题。

误差Matlab的表现是

我除去本地.matlab文件夹。但在此之后，我又面临同样的问题。

请帮我解决这个问题在MATLAB中。先谢谢你。

答案 问题是基本上有太多的文件被打开。

Answer 1

我遇到过类似的问题，正如Petesh所说，它是一个文件句柄问题 - MATLAB一次只能有这么多的打开文件。快速修复是在MATLAB命令窗口中执行fclose all。要检查已打开多少个文件句柄，请使用fopen('all')，这将显示活动句柄的列表。 （我的版本的MATLAB 2013a在512个打开的文件中完整）。

的关键错误消息捡起来产生误差的全部线路的出是

(Too many open files) 

更好的解决办法是，以确保任何脚本，你必须关闭文件打开它们，特别是如果说后，你每次都在循环中打开文件。

参见：How to close file handle in matlab?

Answer 2

我来说也得到了同样的问题。使用FCLOSE（）函数抛出的错误离开封闭循环内的所有打开的文件... 乐趣 M.Santhanakumar

Answer 3

它必须因为你打开一个.txt文件过很多次，但没有关闭它们及时。 试试这个：

fidout = fopen([saveLabel_path, 'new_Label.txt'], 'a'); 
fprintf(fidout, '%s \n', final_label); 
fprintf(fidout, '\n'); 
fclose(fidout); 

，以避免它仍然警告你，只是补充一点： FCLOSE所有; 要当心，因为你将永远不会再看到这个错误，告别它永远...

希望它可以帮助你......

Answer 4

根据哪些文件可能已经打开，而不是关闭，使用Matlab中的$ fclose $函数（例如$ fclose（'myfile'）$）。 我经常使用$ fclose（'all'）$以确保我不会错过任何文件:)

Answer 5

如果你在Matlab中遇到这个错误，路径是一个问题，假设如果你使用任何其他软件，如巨蟒的java，

所以我只好做清除临时文件中，例如

的环境变量，如果你看到像this path in[ C:\Python27\Scripts]在环境变量和去临时删除这一行的错误将是明显的。
