I came across compile error on the ORB example given by the document.
The error is:
Building with 'Xcode Clang++'.
Error using mexOpenCV (line 114)
Undefined symbols for architecture x86_64:
"ocvKeyPointsToStruct(std::__1::vector<cv::KeyPoint, std::__1::allocator<cv::KeyPoint> >&)", referenced from:
_mexFunction in detectORBFeaturesOCV.o
