Undefined function or variable error using Neural Network Toolbox

55 views (last 30 days)
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.
|=========================================================================================|

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

You might want to remove the bracket after shuffle? ;-)
