基于CMake交叉编译C++得到适用与Matlab的Mex加速库文件

提供基于CMake的方式编译C++代码，代替mex函数打包，配置简单，通用，可修改，不依赖于特定的编译器，平台，工具IDE等，本示例展示了使用一个readBinFile.cpp文件如何通过交叉编译为对应平台的mex文件（即不同平台对应的库文件）。

编译后缀文件

• windows: *.mexw64
• Unix: *.mexa64
• Mac: *.mexmaci64

Requirements

• desktop Matlab 2018a or later

How to compile

git clone https://github.com/cuixing158/MexCmake.git
cd MexCmake
mkdir build
cd build
cmake  ..
make 

Then copy "myGccMex" mex file to your MexCmake/ working directory(current working directory).

How to use mex file in matlab

Copy the mex file to the current working directory of matlab and execute the following statement to parse the image.

outImg = myGccMex("dataImgUnrealori.bin");
imshow(outImg)
