This is the ARIMA part of my code

TS2 = TS(:,2);
n2=16;
[fit,VarCov,LogL,info] = estimate(model,TS2(1:n2,1))
AIC = aicbic(LogL,p+q)
res = infer(fit,TS2(1:n2,1));
TSlds = zeros(n1-n2,1);
for i = 1:(n1-n2)
[TSlds(i,1)] = forecast(fit,1,'Y0',TS2(1:(n2-1+i),1));
end

and I get this error:

Error using subsindex
Function 'subsindex' is not defined for values of class 'arima'.
Error in Copy_of_DO05A090_12months (line 124)
[TSlds(i,1)] = forecast(fit,1,'Y0',TS2(1:(n2-1+i),1));

Thanks

I suspect you have a matrix variable called "forecast" somewhere in the workspace. Otherwise, set a breakpoint at line 124 and show us the output of WHOS there.
