Linear Convection Problem at different values of step size of time

Objective: Basically less the step size more is the simulation time as calculation gets higher. Solution is quite unstable for 1e-1 as there are lot of disturbances and, its best for 1e-2 as it seems close to stable, while its quite similar in case for 1e-3 and 1e-4. now the code i used is, clc clear all close all figure(1) tic hold…
