"WebEither write down the likelihood function and feed it into a generic optimizer (such as the function optim in R); Or use an existing function that takes the model specification (e.g. ARMA (p,q)-GARCH (s,r)), "writes the likelihood" for you and optimizes it (such as the function ugarchfit in the "rugarch" package in R). Both ways are fine: " - Garch package matlab
