摘要:用计算机解决数学问题, 我们一般可以把它分为两大类, 一类是数值计算类问题, 另一类是非数值计算类问题。数值计算类问题主要涉及: 函数计算、初( 高) 等方程求根、微积分求解、数论等; 而非数值计算类问题主要涉及: 初(高) 等函数曲线拟合、图论等方面的数学问题。对于数值计算类问题我们通常使用计算机高级语言编程的方法求值, 在这过程中我们会用到一些专门的计算机数值计算的算法。对于非数值计算类问题我们主要使用计算机辅助设计的方式, 采用数学科学计算软件来绘制函数曲线图、拟合图谱。比较常用的软件有matlab,mathematica 数学计算辅助软件。但无论是数值计算类, 还是非数值计算类, 它们都遵循着相同的设计与应用过程。

Abstract: puters to solve mathematical problems, we can generally be divided into two categories, one is the numerical calculation of class, and the other non-puting class. Mainly related to the issue of numerical calculation class: function calculation, (H), etc. Equations in One Variable Calculus solving, number theory, etc.; rather than a numerical calculation the class of problems mainly related to: early (H) function curve fitting, graph theory, etc. mathematical problems. Class of problems for the numerical calculation, we usually use high-puter programming language method evaluated in this process, we will need some puter numerical calculation algorithm. For non-puting class, we mainly use puter-aided design, using the mathematics of puting software to draw the function curve fitting the map. Comparison monly used software Matlab, the mathematica mathematical calculations supporting software. However, numerical calculat
