关于matlab与VS混合编程——在matlab中调试程序

win7 64位
matlab:R2014a
vs: Visual Studio 2017 Community (installed with the VC++ 2015 vc140 toolset)
（http://blog.csdn.net/guoxinian/article/details/50858523）matlab调用C++ 貌似有 利用MEX技术和调用C/C++动态连接库。这里使用MEX技术, mex接口函数的编写（在VS中编写）可参照： http://blog.csdn.net/yimiyangguang185/article/details/52623075 和 http://blog.csdn.net/u010555688/article/details/37659285
写好mex接口函数后（我的是LocalExpansionStereoMex.cpp），需要在matlab中编写文件 然后运行编译生成.mexw64(64位)文件，同时
（http://blog.csdn.net/jpday/article/details/50364882）注意：使用mex编译生成的时候一定要使用mex -g,否则调试的时候不会跳入vs中执行相关跟踪操作。也就是说如果你要在matlab中调试混合编程，那么除了.mexw64还必须生成.mexw64.pdb文件 见代码中标注。下面的代码是在别人写的基础上改动的% http://www.cnblogs.com/lukylu/p/3966871.html % This cppmake.m is for MATLAB

http://blog.csdn.net/jacke121/article/details/56045242中指出“-O3, -DNDEBUG 这两个参数优化选项，可以提高编译出来的程序运行速度” 在运行此matlab文件前需要按照 http://blog.csdn.net/wind_liang/article/details/51402224
中先在命令行窗口中执行 mex - setup和mbuild -setup
最后按照 http://blog.csdn.net/ayw_hehe/article/details/6790147中
“不要关闭matlab， 打开vs       选tools->attach to process...       在跳出来的对话框中选择matlab       然后file->open自己的xxx.c，设置断点       而后直接在matlab中调用刚编译过的程序，搞定
”
开始调试。注意：此处打开VS的时候重新打开一个，不要在别的项目中直接打开。
