我目前正在尝试从glmnet包(http://web.stanford.edu/~hastie/glmnet_matlab/index.html)运行代码。它在此过程中调用mex文件。当我在前两次运行包中的函数时，它工作得很好。每三次尝试，MatLab都会给出一个"灾难性"错误，并要求我关闭它。它可能是与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:

This error was detected while a MEX-file was running. If the MEX-file
is not an official MathWorks function, please examine its source code
for errors. Please consult the External Interfaces Guide for information
on debugging MEX-files.
If this problem is reproducible, please submit a Service Request via:

A technical support engineer might contact you with further information.
Thank you for your help.
总结上面的注释，第一步是使用调试器调试MEX函数。查看这篇关于如何使用基于您正在使用的任何操作系统的IDE来设置它的文章:防止在MATLAB中崩溃MEX文件…因此，在第三次尝试时，找出它在哪一行崩溃。
现在你知道它在哪里崩溃了，你得到了未解决的链接错误。未解决的链接错误来自于试图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文件在运行代码时导致了问题。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。类似地，32位指令在这里:http://web.stanford.edu/~hastie/glmnet_matlab/win32compile.html。您可以跳过指令中的第二步，因为我相信这一步是由最新版本的MATLAB处理的。
希望这将使事情更稳定!
