Force Matlab to run a deep learning code on CPU instead of GPU : I don't have CUDA-enabled NVIDIA GPU and I want to force matlab to run the code on CPU instead of GPU (yes I know, it will be very very slow). How can I do it?

As an example, lets try to run [this code][1]. Here is the error given by Matlab:

    There is a problem with the CUDA driver or with this GPU device. 
    Be sure that you have a supported GPU and that the latest driver is installed.
    
    Error in nnet.internal.cnn.SeriesNetwork/activations (line 48)
                output = gpuArray(data);
    
    Error in SeriesNetwork/activations (line 269)
                    YChannelFormat = predictNetwork.activations(X, layerID);
    
    Error in DeepLearningImageClassificationExample (line 262)
    trainingFeatures = activations(convnet, trainingSet, featureLayer, ...
    
    Caused by:
        The CUDA driver could not be loaded. The library name used was 'nvcuda.dll'. The error was:
        The specified module could not be found.
