New Quant Job

Sorry, but can't read the formulas.

In large dimension PDE-solving could be really expensive. So be tricky and use reduced basis methods.

Rannacher smoothing combined with Crank Nicolson may be a good way to work against wiggling at strike.

Did it works? Did you compare your solution with the exact solution of the closed-form Heston?

I would write a new function as m-file: function y = barrier(sigma, L) r=.... %all given parameters y = pdepe(m,@pdefun_gbm,@pdeic,@pdebc,x,t1,[],r,sigma);

You're welcome to ask! I wrote a short explanatory approach for you.

Hi, derivatives of the call are not only taken with respect to strike K but also with respect to maturity T in place of price S and time t. This is made by an adjoint/backward argument. Maybe this paper by Jim Gatheral will help you (especially section 2.2).

Hi Jarrod, it might be, that you have to use Green's and Stoke's theorem by the solution of PDEs. Green's theorem assists you by calculating integrals on boundaries. Nevertheless to read this special case of both theorems is no problem at all. I guess, that each book on numerical solution of...

You should never lie in your CV and during your interview. Human research managers are too clever!

If you have vector- and matrix-based calculations, MatLab will be first choice. Nevertheless if you have loops (if, while, for, etc.) in your code, MatLab will be very slow. So for a mathematician it is very visceral to use MatLab, but MatLab is not really a programming language.

This seems to be quite good, Frank!
