偏微分方程的数值解法在数值分析中占有很重要的地位,很多科学技术问题的数值计算包括了偏微分方程的数值解问题。在学习初等函数时,总是先画出它们的图形,因为图形能帮助我们了解函数的性质。而对于偏微分方程,画出它们的图形并不容易,尤其是没有解析解的偏微分方程,画图就显得更加不容易了。为了从偏微分方程的数学表达式中看出其所表达的图形、函数值与自变量之间的关系,通过MATLAB编程,用有限元数值解法求解了偏微分方程,并将其结果可视化。
偏微分方程的數值解法在數值分析中佔有很重要的地位,很多科學技術問題的數值計算包括瞭偏微分方程的數值解問題。在學習初等函數時,總是先畫齣它們的圖形,因為圖形能幫助我們瞭解函數的性質。而對于偏微分方程,畫齣它們的圖形併不容易,尤其是沒有解析解的偏微分方程,畫圖就顯得更加不容易瞭。為瞭從偏微分方程的數學錶達式中看齣其所錶達的圖形、函數值與自變量之間的關繫,通過MATLAB編程,用有限元數值解法求解瞭偏微分方程,併將其結果可視化。

The numerical solution of partial differential equations plays an important role in numerical analysis,the numerical calculation of many science technology includes the numerical solution problem of the partial differential equations.In the study primary function,we always draw their graphics,because the graphics can help us to understand the nature of the function.But for the partial differential equations,painting their graphics will not be easy,in particular for the partial differential equations that have no analytical solution,drawing is on the more difficult.In order to looking out the relationship of the mathematical expression of that expression of its graphics,between function values and variables from the partial differential equations,through MATLAB programming,soluted the partial differential equation with Finite Element numerical method,and visualized the results.
