OpticalFlow.cpp代码在MATLAB中的Mex配置

Question

你好，我使用的是光流Matlab/C++代码(源代码).。我在LinuxUbuntu14.04 64位操作系统下使用MATLAB .在配置文件中写着：

编译前，请检查子文件夹"mex“中的project.h文件。如果你使用Windows，你就不用做任何事情。如果您使用Mac或Linux，请取消注释#Define_LINUX_MAC行。

，这已经完成了。另外，它还包括：

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

mex Coarse2FineTwoFrames.cpp OpticalFlow.cpp GaussianPyramid.cpp

我认为，由于未能在MATLAB中正确配置mex编译器，在运行上述mex命令后，我会收到以下错误：。

，请问我怎么解决这个问题？

Answer 1

在Linux服务器上使用MATLAB中的OpticalFlow时，我也面临着这个问题。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
