Forward finite difference
WebKey Differences Between Forwards and Futures. The structural factors in a Futures Contract are quite different from that of a Forward. A margin account is kept in a place … Consider the normalized heat equation in one dimension, with homogeneous Dirichlet boundary conditions One way to numerically solve this equation is to approximate all the derivatives by finite differences. We partition the domain in space using a mesh and in time using a mesh . We assume a uniform partition both in space and in time, so th…
