防止MEX文件在MATLAB中崩溃 [英] Preventing a MEX file from crashing in MATLAB

问题描述

我有一个MEX文件，我从借从别人帮助我编码一个半自动核探测算法。问题是MEX文件偶尔导致分段故障。但是，如果代码第二次使用相同的参数运行，那就没问题了。

I have a MEX file which I "borrowed" from someone else to help me code a semi-automated nuclear detection algorithm. The problem is that the MEX file sporadically causes a segmentation fault. However, if the code is run with the same parameters a second time, it's fine.

我希望MEX文件有一种 try / catch 惯用法，星期六寻找的东西，我找不到任何东西。

I was hoping there was a sort of try/catch idiom for MEX files, but after spending most of my Saturday looking for something, I couldn't find anything.

这个问题的任何帮助将是惊人的！否则，我将不得不将 .cpp 移植到MATLAB中（约10,000行使用数百个依赖项： - （）。

Any help on this issue would be amazing! Otherwise, I am going to have to port the .cpp into MATLAB (and it's around 10,000 lines using hundreds of dependencies :-().

推荐答案

您使用哪个平台？有些方法可以帮助您对MEX文件进行调试每当出现分段错误时，

Which platform are you using? There are methods to help debug your MEX files. Whenever there is a segmentation fault, you can use an IDE to tell you where in the code it's crashing.

NB ： 将OP提及站外链接以帮助他或她的问题。我通常包括我的帖子中的大部分答案，并提供链接作为参考。因为你没有告诉我你使用的平台，我不会为所有平台编写解决方案，因为这将需要太多的时间。因此（我祈祷的链接长期稳定），你可以参考适合你的平台的链接。

NB: I am against referring the OP to a link off-site to help with his or her question. I usually include most of the answer in my posts and provide links as references. Because you haven't told me what platform you're using, I will not write solutions for all platforms as that will take too much time. As such (and I'm praying that the links are stable for a long time), you can refer to the appropriate link for your platform.
