Witryna9 kwi 2016 · 1. I transformed Blacks Scholes equation to a Heat equation. I try to use explicit finite difference method to solve this PDE and get the price of a call option. I also solve for this by using black schols equation "analytically". The problem is that I cannot get more accurate in the numerical result. Here is my Python code. WitrynaThe finite difference method relies on discretizing a function on a grid. To use a finite difference method to approximate the solution to a problem, one must first discretize the problem's domain. This is usually done by dividing the domain into a uniform grid (see image to the right). dancing with the wolves star
