摘要函数性态是微积分学的主要研究内容,有着广泛的应用。但是,有些函数的性态不容易求出来,函数图像也无法便捷地画出来。我们可利用MATLAB软件加以解决。
本文研究了函数的单调性、极值点、凹凸性、拐点和渐近线等函数性态的定义和性质。同时,我们结合具体例子研究了如何利用MATLAB的数值计算、绘图和可视化功能来研究函数的性态。事实上,通过MATLAB控制线形、平面、色彩、光线、视角等属性可以绘制出直观、准确的函数图像,把函数的内在特征表现的淋漓尽致。这能帮助我们高效地解决许多相关数学问题,达到事半功倍的效果。22113

Title Research on the properties of functions and its applications based on MATLAB
Abstract
The properties of functions are an important research topic in the calculus and have many applications. However, it is hard to find out the properties of some functions. Moreover, the image of the function can not be drawn easily. We can use the MATLAB software to solve these problems.
In this paper, we research the properties of functions including monotony, extreme points, convexity, inflection, and asymptotic. We also research how to study the properties of functions by using numerical computing, graphics and visualization capabilities of MATLAB. In fact, we can create the image of function accurately by controlling linear, plane, color, light, perspective and other attributes in the MATLAB. It display the properties of functions perfectly. This helps us solve many mathematician problems efficiently. In fact, it can achieve maximum results with little effort.
