I am following the provided example for Long-Short-Term-Memory networks found in the Neural Network Toolbox (https://de.mathworks.com/help/nnet/examples/classify-sequence-data-using-lstm-networks.html) and whenever I use the code given in the example for training the network

net = trainNetwork(X,Y,layers,options);

I get the following error:

>> net = trainNetwork(X,Y,layers,options);
Training on single GPU.
|=========================================================================================|
|     Epoch    |   Iteration  | Time Elapsed |  Mini-batch  |  Mini-batch  | Base Learning|
|              |              |  (seconds)   |     Loss     |   Accuracy   |     Rate     |
|=========================================================================================|
Error using trainNetwork (line 140)
Undefined function or variable 'endfunction'.
Caused by:
    Undefined function or variable 'endfunction'.

I tried re-installing the toolbox and rehasing the toolbox cache but it does not matter. Also, if I try to use

maxEpochs = 150;
miniBatchSize = 27;
shuffle = 'never';
cpu = 'cpu';
options = trainingOptions('sgdm', ...
    'MaxEpochs',maxEpochs, ...
    'MiniBatchSize',miniBatchSize, ...
    'Shuffle', shuffle), 'ExecutionEnvironment' , cpu);

I get this error message:

>> net = trainNetwork(X,Y,layers,options);
Error using trainNetwork (line 140)
Undefined function or variable 'endfunction'.
Caused by:
    Undefined function or variable 'endfunction'.

It looks like while using the CPU for computation the function does not even start.

Thanks in advance.

endfunction is for Octave code not MATLAB

@Walter I am facing same type problem! I also use your suggestion ( dbstop if caught error ) but it is same. What should I do? In my PC neural network toolbox already installed.

When I run my code it gives me this error

Undefined function or variable 'batchNormalizationLayer'.
Error in leafRNN (line 30)
  batchNormalizationLayer

batchNormalizationLayer needs R2017b or later.
