How do I solve this?

Hi, I'm new and is unsure on how to apply to do google net. I've tried this code and received some errors.

clear

camera = webcam; % Connect to the camera nnet = googlenet; % Load the neural net

 while true   
     picture = camera.snapshot;              % Take a picture    
     picture = imresize(picture,[227,227]);  % Resize the picture

     label = classify(nnet, picture);        % Classify the picture

     image(picture);     % Show the picture
     title(char(label)); % Show the label
     drawnow;   
 end
