[Quantlib-dev] HullWhiteProcess class usage...

[Toyin A. <toy...@ho...>]

Hi All,

I am looking for an example of how one would use the HullWhiteProcess class.
There is already an example of how one would use the HullWhiteForwardProcess 
class within the
mcHullWhite Pricing Engine class.

The key issue for me are (because we do not need to use the 
setForwardMeasureTime() function)
what adjustments needs to be made to a copy of the mcHullWhite  Pricing 
Engine class (within the PricingEngines/CapFloor folder) in order to make 
use of the HullWhiteProcess object instead
(for example - the accrualFactor variable, which discount factors to use for 
discounting the payoff at each period, stochastic, deterministic etc...).

In addition, because these classes are derived from the StochasticProcess1D 
class, will they be processed correctly if used within the 
StochasicProcessArray class. Let's say 2 HullWhiteProcess objects, an FX 
process object along with a correlation matrix.

I know that person(s) from "Banca Profilo S.p.A" initially contributed this 
code so if they or anyone else has an idea of how to the said class, it 
would be great.

Best Regards,
Toyin Akin.
