cirvolspec

Specify Cox-Ingersoll-Ross interest-rate volatility process

Syntax

VolSpec = cirvolspec(Sigma,Alpha,Theta)

Description

VolSpec = cirvolspec(Sigma,Alpha,Theta) creates a Cox-Ingersoll-Ross (CIR) VolSpec.

Examples

Create a Structure Specifying the Volatility for cirtree

Create a Cox-Ingersoll-Ross volatility specification (CIRVolSpec) using the following data.

Alpha = 0.03; 
Theta = 0.02;  
Sigma = 0.1;   
CIRVolSpec = cirvolspec(Sigma,Alpha,Theta)

CIRVolSpec = struct with fields:
    FinObj: 'CIRVolSpec'
     Sigma: 0.1000
     Alpha: 0.0300
     Theta: 0.0200
