Financial Modelling: Theory, Implementation and Practice with Matlab source from Joerg Kienitz and Daniel Wetterau, WILEY, September 2012
Pricing Call Options for advanced financial models using FFT and the Carr-Madan or the Lewis Method. We cover:
Bachelier, Black-Scholes, CEV, Displaced Diffusion, Hull-White
Heston, SABR, Displaced Diffusion Heston, Heston-Hull-White
Merton, Bates, Bates-Hull-White
Variance Gamma, Normal Inverse Gaussian
Gamma Ornstein-Uhlenbeck and CIR clock

Also, The Carr and Madan approach used another formula for pricing out-of-the-money call (indeed the formula for ITM call options is based on the intrinsic value and therefore does not apply to OTM call options).
Why do we not consider another formula for OTM options?
I am trying to use your codes and price the same option with both HestonHullWhite characteristic function and hhw characteristic function.
I want to match both prices. For this reason, I set the correlation rho13 equal to zero in the hhw characteristic function.
But how do I get r0 so that the prices match? I tried from the ircurve but did not succeed... Some help?
Amazing book and code Sirs. Thank-you.
Just one issue: one running >> TestScriptVolSmileHeston
This error pops up:
Maximum variable size allowed by the program is exceeded.
Error in CallPricingFFT (line 53)
uvec = 1:FFT_N;
Error in TestScriptVolSmileHeston (line 52)
FFTopt(j,:) = CallPricingFFT('Heston',S,K,T(j),r,d,vInst,vLong,kappa,omega,rho);
Why is it?
