本程序是使用MATLAB语言采用迎风格式解对流方程，对流方程在工程上有很广泛的应用，而迎风格式的精度比较高还包括用跳点格式解扩散方程的初值问题，所以有两个程序
,This procedure is to use the MATLAB language solution using upwind convection equation, the convection equations in engineering, there is a wide range of applications, and the accuracy of upwind scheme also includes a relatively high point format with jump-diffusion equation solution of the initial value problem, so there are two procedures
