Matlab`s Econometrics Toolbox is great for forecasting, modelling, estimating, and simulating
As I read this, this Matlab Econometrics toolbox is so powerful for these uses using GARCH, the help file includes some very solid examples which are read from Nasdaq source files. Charts and plots are also showcased for quick analysis and understanding. There are heavy uses of GARCH to make all this happen. One powerful function is called garchset.
The help files even includes examples on showing how to:
use the default GARCH(1,1) model to model the Deutschmark/British pound foreign-exchange series.
This simulates both on a single path or multiple path.
Presampling data is also shown with simulations as well.
There are even capabilities to do optimization termination on estimation data.
A great New York Stock Exchange example is used to demonstrate Estimating ARMA(R,M) Parameters. Lower bounder restrained were also included.
As for forecasting capabilities with this Econmetrics toolbox, Asymptotic Behavior can be done as well. Regression in forecasting can be done via:
Using Forecasted Explanatory Data

Generating Forecasted Explanatory Data
Regression in Monte Carlo using some Matlab functions like:
*

garchsim
*

garchinfer
*

Garchpred
There are various multiple time series models supported as well. These include:
Vector Autoregressive VAR(p)

Vector Moving Average VMA(q)

Vector Autoregressive Moving Average VARMA(p, q)

Vector Autoregressive Moving Average with eXogenous inputs VARMAX(p, q, r)

Structural Vector Autoregressive Moving Average with eXogenous inputs SVARMAX(p, q, r)
There is also coverage of Scholastic Differential Equation which includes:
