当我尝试使用 Matlab 进行一些协方差计算时出现此错误。我正在从 win 2008 服务器 64 位应用程序上的 .NET 2.0 应用程序调用 matlab。我从 matlab 得到的异常消息是“评估函数错误，SEGV：严重错误”

I am copying the dump file from the matlab crash. Any help is really appreciated, thanks in advance.

This is the Exception information I see in the Dump file:

**"The Thread tried to read from or write to an virtual address for which it does not have the appropriate access"**

恐怕我不知道是什么导致了您的错误或如何解决它。

但是 MATLAB永远不应该像这样的 SEGV。即使你做了坏事或不受支持的事情，它也应该优雅地出错并告诉你出了什么问题。

如果您可以重现地获得此 SEGV 错误，请将其作为错误报告给 MathWorks。他们可能会或可能不会发现您是否做错了什么，并且可能会或可能不会提出解决方法或解决方案 - 但他们需要了解 SEGV。

向 MathWorks 报告问题时，如果可能，请报告一个可重现的最小案例，并确保描述系统的所有方面（操作系统、MATLAB、.NET 等）。
