用二维热传导分数步长法求解二维热传导方程，其中解转化来的方程用的是追赶法-Solving the two-dimensional heat conduction equation with two-dimensional heat conduction fractional step method, which transformed to the equation solution is to catch up with the law

求解二维热传导方程，文档中有过程和matlab程序。 本文利用有限差分法来求二维热传导方程的数值解，通过Matlab编程求解并作图，进而与解析 解做出的图进行比较，画出误差图。(Solving the two-dimensional heat conduction equation, there are procedures and MATLAB programs in the document. In this paper, the finite difference method is
