What result are you expecting for people who have mustaches or beards, as those are hair?

How about this code from one of the developers of the Computer Vision System Toolbox? http://www.mathworks.com/matlabcentral/fileexchange/47105-detect-and-track-multiple-faces

I don't know. Actually I have no idea what you're referring to. If no code is being run, then no error message can be generated. Something you have must be running and be trying to call or use that thing, and MATLAB doesn't know what that thing is. Could be an array, could be a function, but who knows, since it's not a variable in the program or a function on the search path or in one of your toolboxes?

vision.CascadeObjectDetector can be used to detect whole faces, but also to detect eyes, nose, and mouth separately. So you could detect a face, and then detect eyes, nose and mouth inside the face, and compute a tight bounding box just around those.
