Working with the arima function from the Econometrics toolbox. When I use an AR or an MA model, no problem. However I get an error message when using an ARMA(1,1) model. The self-contained code is
data = randi([-10 10],1,30)';
model=arima(1,0,1);
result=estimate(model,data)
Running this I receive the error message 'Index exceeds the number of array elements (2).'
