How to implement LSTM Time-series prediction using multi-features?

Hello everyone,
I have the attached code and the attached data file here. I want to modify that code to proceed time-series prediction for 1 output using 5 inputs.
When I the training finishes I get the following error:
The prediction sequences are of feature dimension 1 but the input layer expects sequences of feature dimension 4.
Error in multi_lstmOMNI_noStand (line 110)
[net,YPred] = predictAndUpdateState(net,YTrain);
Can you please tell me how to fix it?
I appreciate your help.

Hello people; I found the problem; the key is in the correct loading of data as the published documents say. I attach my code and used tables so you don't have problems to run it; I upload data from excel to train and test. I do not use standardized data. The model fits quite well. Cheers

Hi Marcelo, i am really new in this topic and i am trying to predict time series of Y depending on two external variables (X1 and X2). I have two questions. (i) Why don’t you use the “predictAndUpdateState” and why do you use the “predict” statement? Is it used for time series prediction? (ii) Why are the previous y values not input into this function? Only x values are input.
