一维扩散方程的有限差分法,采用了追逐法求解三对角矩阵，对一维扩散模型进行了分析，使用隐式六点差分格式(Crank-Nicolson)基本思想进行隐式差分。(The finite difference method of one-dimensional diffusion equation is used to solve the three diagonal matrix by chase method. The one-dimensional diffusion model is analyzed, and the implicit six difference scheme (Crank-Nicolson) is used to carry out implicit difference.)
