Too many input arguments - ARIMA model selection

Good Afternoon , I get the error :

" Error using arima

Too many input arguments.

Error in CPIForecasting (line 42)

mdl = arima(p,0,q);"

For this code:

pmax = 4; qmax = 4;

aic=NaN(pmax+1,qmax+1); bic = aic;

const = 1;

for p = 0:pmax

for q = 0:qmax

mdl = arma(p,0,q);

[~,~,logL] = estimate(mdl,y,'Display','off');

kk = (p+q+1); nobs=size(y,1)-pmax;

aic(p+1,q+1) =(-2*logL/nobs)+(2*kk/nobs);

bic(p+1,q+1) = (-2*logL/nobs)+(2*kk*log(nobs)/nobs);

end

end

I am trying to estimate the model by using the BIC.

In code, it is mentioned as arma(p, 0, q).

I guess it should be arima(p, 0, q).
