Witryna10 lut 2024 · By nature, the finite-difference method propagates the solution from time k to time k+1, so we have to keep the outmost loop : the k-loop. But the 2 inner loops can be simplified a lot. Remember the above dot product : with a sum-product operation, we can compute the temperature at time k+1 for a position i,j. But numpy allows doing … WitrynaSchwarz [5]. The most common finite difference methods for solving the Black-Scholes partial differential equations are the • Explicit Method. • Implicit Method. • Crank Nicolson method. These schemes are closely related but differ in stability, accuracy and execution speed, but we shall only consider implicit and Crank Nicolson schemes.
