我目前正在尝试从glmnet包中运行代码（http://web.stanford.edu/~hastie/glmnet_matlab/index.html）。它在此过程中调用 mex 文件。当我前两次运行包中的函数时，它工作正常。每三次尝试，MatLab 都会给出一个“灾难性”错误并要求我关闭它。它可能与来自 mex 文件的内存分配有关吗？我想知道这是否可能是 mex 文件用户的常见问题。谢谢。

编辑：这是“灾难性”错误：

总结我们上面的评论，首先使用调试器完成 MEX 函数。查看这篇文章，了解如何根据您使用的任何操作系统使用 IDE 进行设置：防止 MEX 文件在 MATLAB 中崩溃……所以在第三次尝试时，找出它在哪一行崩溃。

既然您已经知道它在哪里崩溃了，那么您就会得到未解决的链接错误。未解决的链接错误来自尝试使用没有可用代码定义的代码/函数。听起来好像有预编译的 MEX 文件会在您运行代码时导致问题。尝试重新编译代码，使其与您的系统最兼容。

64 位 Windows 的说明在这里：http ://web.stanford.edu/~hastie/glmnet_matlab/win64compile.html 。同样，32 位指令在这里：http ://web.stanford.edu/~hastie/glmnet_matlab/win32compile.html 。您可以跳过说明中的第二步，因为我相信这一步是由更新版本的 MATLAB 处理的。

希望这将使事情更加稳定！
