Hello guys this is my first time in stackoverflow and i am new as a matlab user(2019b). I have a problem with armax model.First of all i want you to describe you my exercise so i have a signal with input x and output y with 10000 value each and i need to pick 8090 values each of those 10000, all good so far i didnt have any problems but i am making my iddata as you will see and after i use armax function and i have this error: `

Operation terminated by user during ltk2>vfilter (line 74) 
    In SHM (line 419)
    models{order2} = armax(DATA,[order2 order2 order2 1]);

Also i need to use the <> function after for my exercise. If someone can help me i will apreciate that . THANK you very much.

`'For ARMAX MODEL NOW:';
min_k = input('Give minimum order (k): \n');
max_k = input('Give maximum order (k): \n');  

for order2 = min_k:max_k
DATA = iddata(Ye,Xe,1/fs,'ExperimentName','SIGNALS')
models{order2} = armax(DATA,[order2 order2 order2 1]);
modal{order2} = the_modals(models{order2}.c,models{order2}.a,fs,1,1); % See Auxiliary Functions
end

`

  • Please [edit] your question to make it a [mcve] - what are `min_k` and `max_k` when you get this error? What is `iddata`? And it's unclear what you mean about needing to use "the <> function". – Wolfie Nov 22 '22 at 15:12
