How to price forward starting European call option

101 Views Asked by At

I have to price a European call option under the Heston model. I have been given a characteristic function (corresponding to the heston model and forward starting call option). I have no idea what to do with this characteristic function and I do not know what Matlab package to solve this with. I have downloaded CFHtoolbox, but can not find a solution there Thanks a lot, because I am stuck with this problem for 2 weeks now.
