How to remove a error with GARCH model forecasting ?

2 views (last 30 days)
Hello,
When I run the example code mentioned here :
load Data_EquityIdx nasdaq = Dataset.NASDAQ; r = price2ret(nasdaq); N = length(r);
% Fit a GARCH(1,1) model to the data.
model = garch(1,1); fit = estimate(model,r);
% Forecast the conditional variance for 500 days using the fitted model. Use the observed returns as
% presample innovations for the forecast.
Vf = forecast(fit,500,'Y0',r);
...and after the last line I get this annoying error: " Error using subsindex Function 'subsindex' is not defined for values of class 'garch'. "
I believe this error stems from a function name conflict - several different functions have the same name "subsindex". After searching the Matlab folder I get these functions with the same name "subsindex":
