在this link中，MATLAB代码带有用于SLIC算法实现的mex文件。
我通过编写mex slicmex.c在MATLAB中构建它。
然后我运行slicmex但收到此错误：
Matlab has encountered an internal error and needs to be closed.
答案 0 :(得分：0)
<强>更新
我最终修复了代码。在MEX文件源中，将行int* dims;更改为const mwSize* dims;。现在应该工作。
问题是代码不是64位友好的，并且对int的大小做了一些错误的假设。
我编译了他们用Visual Studio 2013提供的代码，从Matlab运行时生成的MEX文件出现致命错误。好像他们在某处划分为零。此时，您可以（1）联系原作者并让他们查看它或（2）自己修复代码。我在下面包含了错误消息和堆栈跟踪：

Thank you for your help.
答案 1 :(得分：0)
我遇到了很多这些mex错误，这使得MATLAB崩溃了。
我想mex函数需要一些你没有给出的具体输入。
你知道，mex使用c / c ++指针访问输入数据，所以如果输入数据类型错误或输入数据错误，指针可能会超出范围。
最常见的情况是mex需要单个类型输入，但是你给出了一个double类型值，这是MATLAB中的默认数据类型。
我建议您检查一下mex源代码，找出所需的数据类型和输入数量。在C / C ++中，float *对应于MATLAB中的single，而double *对应于MATLAB中的double。
就是这样。希望你能解决它。
