Write a matlab code for the following... apply Dirichlet boundary conditions. Thanks! the diffusion equation uses the always unstabie. 9. The DuFort-Frankel scheme for solving discretization: 2T h2 Note that this is a three time-level scheme, that is, the method uses Tn41 7m-1, so the scheme is not self-starting. Write a program that uses this scheme to solve the diffusion problem discussed in this section. Use the FTCS scheme on th first step to get it started. Try a variety of values for ? and show that the methodis unconditionally stable but that the accuracy of the solution decreases with increasi r. |Computer] 7m 7, and Write a matlab code for the following... apply Dirichlet boundary conditions.
