Undefined function or variable 'prepareDataTrain'

Hi, I'm using Matlab 2018a on Ubuntu 17.10 (x64) and I'm following this example to make an LSTM with regression https://it.mathworks.com/help/nnet/examples/sequence-to-sequence-regression-using-deep-learning.html But when I call the method prepareDataTrain, I have this error:

Undefined function or variable 'prepareDataTrain'

The function source is at the end of the document under the section Example Functions.

Ops, didn't see that, thank you!

Dear Francesco Bosso,

Did you get your problem resolved ? How to use the function source which is at the end of the document ? I am also getting the same error as yours. Thanks

[Jose Matías]

Hi,

Copy the source into a m-script and save it in the curren folder with the name of the function (e.g. prepareDataTrain.m).

When you visit https://www.mathworks.com/help/deeplearning/examples/sequence-to-sequence-regression-using-deep-learning.html then near the upper right there is a place to click to "Try it in MATLAB". Clicking that will give you a command you can copy to run the code. It will copy the appropriate files for you.
