hi i'm using matlab 2013a x64 and win7 x64 . install the opencv path (C:\opencv)
Compile Error :
>> mex -LC:\opencv\build\x64\vc11\lib -IC:\opencv\build\include\opencv -lcv -lcxcore me_HaarDetectOpenCV.cpp

Could you confirm that libcv.lib or cv.lib are in C:\opencv\build\x64\vc11\lib ?

i'm using code to the created the MEX file (me_HaarDetectOpenCV.mexw64)
mex -largeArrayDims -I'C:\opencv\build\include' -L'C:\opencv\build\x64\vc11\lib\realese' -lopencv_core247 -lopencv_imgproc247 -lopencv_objdetect247 me_HaarDetectOpenCV.cpp

To check: you solved the problem? If so, would was the key change you needed to make?

You do not have the cv library that it needs to link against, or else you have the library in a different directory.
Perhaps you downloaded opencv but did not tell it to compile itself.

@ Walter Roberson i'm edit me_HaarDetectOpenCV.cpp :
#include "D:\Program Files\MATLAB\R2013a\extern\include\mex.h"
#include "C:\opencv\build\include\opencv\cv.h"
#include "C:\opencv\build\include\opencv\highgui.h"
#include "C:\opencv\build\include\opencv\cxcore.h"
but compile error :
