MATLAB Error: Unrecognized function or variable 'FeaturesFinder_'.

[preethamam]

I have installed the OpenCV on the MAC OS using homebrew and made sure that the

$ make MATLABDIR=/Applications/MATLAB_R2016a.app PKG_CONFIG_MATLAB=opencv3 LDFLAGS=-L/usr/local/share/OpenCV/3rdparty/lib -j2 was successful.

I am trying to run the stitching_detailed_demo.m example and but having the error:

Finding features...
Unrecognized function or variable 'FeaturesFinder_'.

Error in cv.FeaturesFinder (line 55)
this.id = FeaturesFinder_(0, 'new', finderType, varargin{:});
