MATLAB 遇到内部错误，需要关闭

Question

我刚刚为64位Mac安装了新的MATLAB R2013b，我的操作系统是OS X 10.8.4。 我遇到了一个一致的问题，这是我在R2013a上从未遇到过的。当我运行我的一个脚本（见下文）时，整个脚本都正常，但随后我不断收到错误消息"MATLAB 遇到内部问题，需要关闭"。然后我必须关闭 MATLAB。

我有一种感觉，因为我是 MATLAB 的新手，所以我在安装的某个地方搞砸了，但我不确定。

这个完全相同的脚本在 R2013a 上仍然运行良好，我尚未卸载它。脚本（利用Psychtoolbox）是一个实验，它打开一个屏幕，显示一些文本，呈现一个音频文件，并要求参与者用6次击键做出回应。此脚本仅显示两个音频文件，因为我只是在测试它。

所有循环似乎都适用于两个版本的 MATLAB，并且屏幕在最后关闭（仅在 2 次通过主循环后发生）。我认为这意味着脚本正在工作，但后期阶段的某些内容导致了问题。

任何和所有的想法都非常感谢！

Answer 1

这种错误通常表示发生了剧烈且不可恢复的事情。看来Psychtoolbox包含MEX文件，这可能是最有可能的罪魁祸首。我会尝试使用 R2013b 重建它们，或者联系作者看看它们是否有与 R2013b 兼容的版本。

Answer 2

这种崩溃可能是由于OSX 10.8.4中的一个新错误，导致PsychToolBox在关闭与显示服务器的连接时崩溃（显然带来了MATLAB）。有关讨论和解决方案，请参阅此处。

任何仍然有此问题的人，请更新到最新版本的PsychToolBox（这总是一个好主意！
