After you call videoinput set ReturnedColorSpace to 'grayscale'.
vidobj = videoinput(theVideoAdaptor, cameraDeviceID, selectedCameraFormats{selectedFormatIndex});
vidobj.ReturnedColorSpace = 'grayscale';

Maybe - with my Logitech demo you might have to debug it and figure out what the adapter name of your camera is and replace Logitech with your computer camera's name.
