I got this error from this code but not sure why even though i just copy it from the mathworks. i have already update my matlab to 2017b.
load JapaneseVowelsTrain
figure
for i = 1:12
subplot(12,1,13-i)
plot(X{1}(i,:));
ylabel(i)
xticklabels('')
yticklabels('')
box off
end
title("Training Observation 1")
subplot(12,1,12)
xticklabels('auto')
xlabel("Time Step")
error:
Undefined variable "X" or class "X".
Error in lstm (line 6)
plot(X{1}(i,:));
any help would be appreciated.

You have asked this some days ago already: https://www.mathworks.com/matlabcentral/answers/375923-implement-to-predict-japanesevowelstrain-as-the-same-in-mathworks . Walter has answered:
JapaneseVowelsTrain does not contain a variable named X: it
contains a variable named XTrain
Why do you ask for "X" again now?

the previous error was Cell contents reference from a non-cell array object.
now get another error.
Undefined variable "X" or class "X".
I have re-opend the matlab again and the problem solved.
sorry a bit new to matlab that's why i ask the community for help.
thanks anyway
