@IaBogdi Finally, I think I get the cause. If anybody is using LAPACKE, then the following line of code is NOT correct: `LAPACKE_dggev(xxxx)` It should not be ROW_MAJOR, but COL_MAJOR.

Solution: find the `error` function in the cpp file. change the `char *` to `std::string`. I guess you will also meet some errors concerning the `vector`, then add `using namespace...

if you open D:\Program Files\opencv_2.4.9\build\x64\vc11\lib can u see opencv_core249.lib, etc?

try uncomment the following code, and make a visual studio project using this pure c++ code (no mex functions are used). Once you have successfully compiled the code and run...
