MATLAB 中用于 OpticalFlow.cpp 代码的 Mex 配置

Question

你好， 我正在使用光流 Matlab/C++ 代码 (source code)。我在 Linux-Ubuntu 14.04 64 位操作系统下使用 MATLAB。在配置文件中它说：

在编译之前，请检查子文件夹“mex”中的 project.h 文件。如果您使用 Windows，则无需执行任何操作。如果您使用 Mac Os 或 Linux，请取消注释 #define _LINUX_MAC 行。

这已经完成了。同样如下：

在 Matlab 中，适当配置 mex 后，将目录更改为“mex”并运行以下命令：

mex Coarse2FineTwoFrames.cpp OpticalFlow.cpp GaussianPyramid.cpp

我认为是由于在 MATLAB 中没有正确配置 mex 编译器，运行上述 mex-command 后收到以下错误：

请问我该如何解决这个问题？

Answer 1

在 Linux 服务器上的 MATLAB 中使用 OpticalFlow 时，我也遇到了这个问题。我通过添加一个选项 -compatibleArrayDims 来解决这个问题，

mex -compatibleArrayDims Coarse2FineTwoFrames.cpp OpticalFlow.cpp GaussianPyramid.cpp
