can you give me a basic c++ code that inclue opencv libraries , and can call the matlab engine ? the file should compile using matlab mex.
(my problem is when I use the engine and compile it with "mex -f optionfile file.cpp"I get error message "cannot include opencv\cv.h" , but using the opencv without the engine its work using the mex file.xpp)
You need Matlab engine if you want to run .m files outside of Matlab command window (e.g. bash, c++ source file, etc.)
In your case, mex program (Matlab External Interface which acts like g++ or other c++ compilers) is required to compile a c++ source file. You must provide mex program a source file which is written according to what Matlab has introduced in its documentation.
If your source code (.cpp file) is including opencv/cv.h file and using one of its methods, you need to link the appropriate library (say libopencv.so, libopencv.dll or etc,) using -l flag. (I use mex foo.cpp -l opencv_core)
I hope it helps, you can provide your source
