for i = 1:app.count
net = networks{i};
temp = dataStandardized{i};
XTrain = temp(1:app.Timer.TasksExecuted-2);
YTrain = temp(2:app.Timer.TasksExecuted-1);
net = predictAndUpdateState(net,XTrain);
[net,YPred] = predictAndUpdateState(net,YTrain(end));
[net,YPred(:,app.Timer.TasksExecuted)] = predictAndUpdateState(net,YPred(:,app.Timer.TasksExecuted-1),'ExecutionEnvironment','cpu');
%Unstandardize the predictions
YPred = app.sig{app.idxFailDs(i)}.*YPred + app.mu{app.idxFailDs(i)};
app.C(app.idxFailDs(i)) = YPred;
app.EditField.Value = "Predicted for "+ app.count +".";
app.Lamp.Color = [1 1 0];
end
I have trained several LSTM networks stored in a cell array and being called in the loop, one at a time.
However the code is not running as I want to and the Command Window says to the effect that the function predictAndUpdateState is not defined for type double arguments.
But the arguments of type double arrays in the network were tested by me in a separate live script; working perfectly fine.
Please suggest a solution for using my LSTM networks in App Designer.

The error doens't necessarily mean it cannot work with double type parameters. I may also be that it cannot find the function. Make sure the function def file is in the same directory as the app you are creating in app designer. You may check visibility of the file using which()
>> which predictAndUpdateState
