MATLAB 中的 Mex 配置，用於 OpticalFlow.cpp 代碼

Question

您好，我正在使用光流 Matlab/C++ 代碼（源代碼）。 我在 Linux-Ubuntu 14.04 64 位操作系統下使用 MATLAB。 在配置文件中它說：

在編譯之前，請檢查子文件夾“mex”中的 project.h 文件。 如果您使用 Windows，則無需執行任何操作。如果您使用 Mac Os 或 Linux，請取消注釋#define _LINUX_MAC 行。

這已經完成了。 它也遵循：

在 Matlab 中，適當配置 mex 后，將目錄更改為“mex”並運行以下命令：

mex Coarse2FineTwoFrames.cpp OpticalFlow.cpp GaussianPyramid.cpp

我認為是因為未能在 MATLAB 中正確配置 mex 編譯器，我在運行上述 mex 命令后收到以下錯誤：

請問我該如何解決這個問題？

Answer 1

在 Linux 服務器上使用 MATLAB 中的 OpticalFlow 時，我也遇到了這個問題。 我通過添加一個選項 -compatibleArrayDims 來解決這個問題，

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