Undefined function or variable 'lstmLayer': Missing Neural Network Toolbox functions

6 views (last 30 days)
I'm trying to follow the Classify Sequence Data Using LSTM Networks tutorial but MATLAB gives me multiple errors when I try to run it.
Many of the functions used in the tutorial couldn't be found giving the error 'Undefined function or variable "function"'. I checked if the Neural Network Toolbox was properly installed and lincensed (which was) and tried to find the respective files in MATLAB nnet toolbox directory (which I dindn't find).
I can run different nnet tutorials like Create Simple Deep Learning Network for Classification where the system succeeds on finding the imageInputLayer function, although it failed previously to find the lstmLayer function.

Which release of Neural Network Toolbox are you using? You can check this using the ver function.

Hello . I hope you have a good day. I sent the article to your service. I implemented the coding part in the MATLAB software, but to implement my network, two lines of setlayers, training MATLAB 2014 give me an error. What other function do you think I should replace? Do you think the codes I wrote are correct?( I used gait-in-neurodegenerative-disease-database in physionet website.) Thanks a lot
