Define width for 'cell'

I am following a guide in mathworks for creating CNN, but I keep getting

   Undefined function 'width' for input arguments of type 'cell'.
   Error in CNN (line 34)
   fullyConnectedLayer(width(varoaDataset))

I am using the following code:

   %%Image input layer
   inputLayer = imageInputLayer([19 19 3]);

   %%Middle layer
   % Layer parameters - related to input layer
   filterSize = [3 3];
   numFilters = 19;

   % Creating middle layer
   middleLayers = [
   convolution2dLayer(filterSize, numFilters, 'Padding', 1)
   reluLayer()
   convolution2dLayer(filterSize, numFilters, 'Padding', 1)
   reluLayer()
   maxPooling2dLayer(3, 'Stride', 2)
   ];

   %%Final layers

   finalLayers = [
    fullyConnectedLayer(64)

    %ReLU
    reluLayer()

    %Messurement of image using loss layer
    fullyConnectedLayer(width(varoaDataset))

    % Softmax loss layer and classification layer
    softmaxLayer()
    classificationLayer()
    ];

   %%Combine layers
   layers = [
    inputLayer
    middleLayers
    finalLayers
    ];

For anyone looking to help, it seems that the OP is trying to replicate the example from this documenation page. (OP, can you please confirm?)

Yes, that is the one I am working from.

My best guess, from the information that you have provided, is that you have stored your data in a cell array named varoaDataset, but the example in the documentation expects those data to be stored in a table.
