More in detail, the user can specify:

- the Itô or the Stratonovich SDE to be simulated. This can be a user defined SDE or an SDE chosen from the

- the SDE structural parameter values;

- the number of the SDE's solution trajectories to be simulated;

- the numerical integration method (Euler-Maruyama or Milstein);

- the time interval [

- the integration stepsize;

- the parameter estimation method;

to obtain (see also the screenshots):

- parameter estimates and confidence intervals;

- plot(s) of the solution trajectories;

- plot(s) of the trajectories empirical mean, together with their 95% confidence bands and the 1st and 3rd quartiles;

- histogram(s) of the trajectories distribution at the endtime

- Monte-Carlo statistics of the solution process at the endtime

Only MATLAB base is required to run the toolbox.

From a numerical point of view, users are highly encouraged in giving a look into the References section, in particular the excellent monographies [1,2] and the article [3], the latter giving a MATLAB-based introduction to SDE simulation. Other useful references for numerical methods are [4,5,6,7]. Highly specialistic references for SDE theory and stochastic calculus are [8,9,10,11]; important references for parameter estimation of diffusion processes are [12,13]. See also the Toolbox User's Guide and references therein.

Take a look at the pdf User's Guide (~3.4 Mb). I suggest to download it (click the right mouse button and select "save target as") instead of open it with a browser.
