How can I import data from Excel for control MIMO system with narxnet function? I have 5 inputs and 1 output, each with 150 training data.

%%1. Importing data this is for SISO model
S = load('magdata');
X = con2seq(S.u);
T = con2seq(S.y);
%%2. Data preparation
N = 300; % Multi-step ahead prediction
% Input and target series are divided in two groups of data:
% 1st group: used to train the network
inputSeries = X(1:end-N);
targetSeries = T(1:end-N);
inputSeriesVal = X(end-N+1:end);
targetSeriesVal = T(end-N+1:end);
%%3. Network Architecture
delay = 2;
neuronsHiddenLayer = 50;
% Network Creation
net = narxnet(1:delay,1:delay,neuronsHiddenLayer);
%%4. Training the network
[Xs,Xi,Ai,Ts] = preparets(net,inputSeries,{},targetSeries);

Dear Lejla,
for simplefy your work, convert your excel to .mat matlab file abd then import your multiple input multiple output data for inputs and targets using:
load('input.mat');
X = tonndata(inputData(:,(1:3)),false,false);
T = tonndata(inputData(:,1),false,false);
and then enjoy your code
sincerely,
