I need the MATLAB code to solve the question below.

The code with initial condition from page 89 is below.

Solve the linear advection-diffusion equation, with the boundary conditions u(-1,t) -u(1,t) - 0 and the initial condition from the code on page 89. In place of ux, use the centered finite difference matrix ?0 -1 0 1 2h Solve the linear advection-diffusion equation, with the boundary conditions u(-1,t) -u(1,t) - 0 and the initial condition from the code on page 89.
