Getting Error while using Preparet. "Index exceeds matrix dimensions. Error in preparets (line 293) xi = xx(:,FBS+(​(1-net.num​InputDelay​s):0));"

My code is

clc
clear all
filename = 'input_import2.xlsx'
x = xlsread(filename);
filename = 'input_ex_cog_import_export2.xlsx'
t = xlsread(filename);
size(x)
size(t)
setdemorandstream(491218381)
net = narxnet(1:2,1:2,10);
view(net)
[Xs,Xi,Ai,Ts] = preparets(net,x,{},t);
[net,tr] = train(net,Xs,Ts,Xi,Ai);
nntraintool
plotperform(tr)
Y = net(Xs,Xi,Ai);
perf = mse(net,Ts,Y)
plotresponse(Ts,Y)
E = gsubtract(Ts,Y);

ploterrcorr(E)
net2 = closeloop(net);
view(net)
[Xs,Xi,Ai,Ts] = preparets(net2,x,{},t);
Y = net2(Xs,Xi,Ai);
plotresponse(Ts,Y)
net3 = removedelay(net);
view(net)
[Xs,Xi,Ai,Ts] = preparets(net3,x,{},t);
Y = net3(Xs,Xi,Ai);
plotresponse(Ts,Y)

and output is

ns =

       1   321

ans =

       1   321

Index exceeds matrix dimensions.

Error in preparets (line 293)
xi = xx(:,FBS+((1-net.numInputDelays):0));

Error in mycode4 (line 12)
[Xs,Xi,Ai,Ts] = preparets(net,x,{},t);

[rabi darji]

i need the answer too for that as i am facing same problem

[Greg Heath]

You are using the same notation for open loop and close loop ...ARRRRGGGGHHHH

What are the matrix and cell sizes of inputs x & X = cell(x)and targets t & T = cell(t). They are not necessarily the same !

The following tends to make life less frustrating for others:

1. Lower case reals and UPPER CASE CELLS

2. Noting sizes with % comments, e.g.,

 [ Im N ] = size(x)  % [ 3  100 ] "m" ==> matrix
 [ I  N ] = size(X)  % [ 1 100  ]

3. Subcripts o and c for openloop and closeloop, respectively

Hope this helps.
