The error in a method's solution is defined as the difference between the approximation and the exact analytical solution. The two sources of error in finite difference methods are round-off error, the loss of precision due to computer rounding of decimal quantities, and truncation error or discretization error, the difference between the exact solution of the original differential equa… Witryna29 paź 2010 · Include the section of code that actually performs the finite difference, the number of points you calculate at (i.e. your mesh size) and how fast it runs vs how fast you think it could / would like it to – J Richard Snape May 31, 2015 at 8:31 Then, open another question or place a comment on this? – Riccardo De Nigris Jun 1, 2015 at 8:16

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. maria\u0027s barber shop countryside ilWitrynaAlways look for a way to use an existing numpy method for your application. np.roll () will allow you to shift and then you just add. I learned to use convolve () from comments on How to np.roll () faster?. I haven't checked if this is faster or not, but it may depend on the number of dimensions. maria\\u0027s big house of hope luoyang chinaWitrynaA Python 3 library for solving initial and boundary value problems of some linear partial differential equations using finite-difference methods.
