I'm trying to use the MATLAB Support Package for USB Webcam. When i run the command "webcamlist" it shows me my webcam: 'HP Wide Vision HD'. But when I try this command : "cam = webcam" it gives me this error in MATLAB:

Warning: The following error was caught while executing 'matlab.webcam.internal.WebcamController' class destructor:
Dot indexing is not supported for variables of this type.
Error in matlab.webcam.internal.WebcamController/delete
Error in matlab.webcam.internal.WebcamController
Error in matlab.webcam.internal.webcamDesktop
Error in webcam (line 95)
                    obj.webcamImpl = matlab.webcam.internal.webcamDesktop(varargin{:}); 
> In matlab.webcam.internal.WebcamController
  In matlab.webcam.internal.webcamDesktop
  In webcam (line 95) 
Error using webcam (line 116)
Error initializing media source.

I'm using MATLAB 2018a. Could someone help me ?

Unfortunately the defining class is a .p file so we cannot look at the source code.
