WebThe usual approach in FDM is to use a central difference approximation to produce the following formula: ∂ 2 C ∂ S 2 ≈ C ( S + Δ S, T, σ, r, K) − 2 C ( S, T, σ, r, K) + C ( S − Δ S, T, σ, r, K) ( Δ S) 2 At this stage we will keep the code procedural as we wish to emphasise the mathematical formulae.
