simple model that is built on a stochastic volatility is the Heston model which A simple Matlab routine demonstrates the a simple simulation of the Brownian.

Use heston objects to simulate sample paths of two state variables. Each state variable is driven by a single Brownian motion source of risk over NPeriods consecutive observation periods, approximating continuous-time stochastic volatility processes. Heston models are bivariate composite models.

The basic Heston model assumes that S t, the price of the asset, is determined by a stochastic process: = + where , the instantaneous variance, is a CIR process: = (−) + and , are Wiener processes (i.e., continuous random walks) with correlation ρ, or equivalently, with covariance ρ dt.. The parameters in the above equations represent the following: * A groundbreaking book dedicated to the exploration of the Heston model a popular model for pricing equity derivatives * Includes a companion website, which explores the Heston model and its extensions all coded in Matlab and C# * Written by Fabrice Douglas Rouah a quantitative analyst who specializes in financial modeling for derivatives for pricing and risk management Engaging and Tap into the power of the most popular stochastic volatility model for pricing equity derivatives Since its introduction in 1993, the Heston model has become a popular model for pricing … - Selection from The Heston Model and its Extensions in Matlab and C#, + Website [Book] Option price by Heston model using numerical integration: optSensByHestonNI: Option price and sensitivities by Heston model using numerical integration: Topics. Agency Option-Adjusted Spreads. Run the command by entering it in the MATLAB Command Window. Option price by Heston model using numerical integration: optSensByHestonNI: Option price and sensitivities by Heston model using numerical integration: Topics.

Each Heston model consists of two coupled univariate models: A geometric Brownian motion ( gbm) model with a stochastic volatility function. This model usually corresponds to a price process whose volatility (variance rate) is governed by the second univariate model. Price Vanilla Instrument Using Heston Model and Multiple Different Pricers Open Live Script This example shows the workflow to price a Vanilla instrument when you use a Heston model and various pricing methods. In finance, the Heston model, named after Steven Heston, is a mathematical model describing the evolution of the volatility of an underlying asset. It is a stochastic volatility model: such a model assumes that the volatility of the asset is not constant, nor even deterministic, but follows a random process . volatility models that pre-date Steve Heston’s model.

This model usually corresponds to a price process whose volatility (variance rate) is governed by the second univariate model. Functions.

A fair generation of random numbers around the mean surges employing a mean reverting model on volatility process.

As before mentioned Beta is the factor which controls the speed of this mean reversion mechanism in the volatility process.

Also by considering equation (1), these factors are easily traceable on the general form of SDEs.

I am not an expert in the Heston model but i recommend the following book: " The Heston Model and Its Extensions in Matlab and C# ". This book provides some Matlab codes on the Heston model. The Heston model was introduced by Steven Heston’s A closed-form solution for options with stochastic volatility with applications to bonds an currency options, 1993. The authors provide a useful function called ‘callHestoncf’, which calculates these prices in R and Matlab. Simpli–ed Derivation of the Heston Model by Fabrice Douglas Rouah www.FRouah.com www.Volopta.com Note: A complete treatment of the Heston model, including a more detailed derivation of what appears below, is available in the forthcoming book "The Heston Model and its Extensions in Matlab and C#", available September 3, 2013 from John Wiley This MATLAB function simulates NTrials sample paths of Heston bivariate models driven by two Brownian motion sources of risk.
