@berak Thanks for your comment. But your recommendation didn't resolve my problem as details are in my updated question above. Any idea what might be wrong? Thanks

I managed to compile and install OpenCV 3.0 and Matlab Code Generator. And in my Matlab, I was able to imread and imshow through cv.

But those functions seemed to be all I can do with "OpenCV Toolbox." For example, if I tried cv.dft, I got Matlab crashed. Actually, I couldn't easily find any cv function that does not make MATLAB crash - except for imread and imshow. Is this the reason that this modules is not a part of official OpenCV module or was something wrong in my build?

Downloaded and compiled OpenCV 3.0 gold with VS2013 without any problem. The new build created all necessary dlls and also _perf_.exe and _test_.exe files for testing. Regarding this, I have a couple of questions.

1. How can I run all perf_.exe and test_.exe? I couldn't find any way to do this so I simply made a batch file to run every test files and put their results into a text file. I wonder if this is a right way.

2. Looking at test results from _test_.exe files, most of tests passed but there are some (sometimes hundreds) tests failed. Is this normal? Considering these tests are unit tests, I think they should all pass. Does this mean my build has a problem?

UPDATE: As berak recommended, I've downloaded necessary files and set the system variable OPENCV_TEST_DATA_PATH, but still get many errors like following in opencv_test_core.exe. So question #2 still stands.

[ RUN ] OCL_Arithm/Pow.Mat/0 unknown file: error: SEH exception with code 0xc0000005 thrown in the test body.

[ FAILED ] OCL_Arithm/Pow.Mat/0, where GetParam() = (CV_32F, Channels(1), fals e) (131 ms)
