Index exceeds array bounds

I've been trying to implement the following piece of code (function)...

but, I get this message in the command window:

Error in LSTMTest>prepareDataTest (line 212)

X = XTest{i};

I looked at similar cases in the forum, but still...

Please how can I solved this issue?

Thank you for your time!

Best regards,

The best way to troubleshoot problems with indexing issues is to look at what is actually stored in the variables in the watch menu on the right hand side of the matlab screen. Check to see if XTest has anything actually stored into it (that would be my first guess, since it can't access the ith element of XTest. Maybe it does not exist).

Thank you for your feedback. Actually, XTest does embody a set of data (it does exist).

Use the debugger and the Pause on errors option. It will land you in the code at the exact location and index within the for loop that the error occurs. Then it will be trivial to see in the workspace and/or using command line what the problem is.
