分段函数的运算与可视化的MATLAB实现

The MATLAB realization of operation and visualization of subsection function

探讨了应用MATLAB实现分段函数的绘图并求出给定点处的函数值。通过MATLAB提供的图形用户界面(GUI)进行设计开发,完成用户输入的各种分段函数的计算,通过单击按钮绘出相应分段函数的图像并且给出其函数值。

This paper discussed that how to realize the plot of the subsection function and numeration of the functi,n value in given point using MATLAB. Through the GUI offered by MATLAB the numerations of kinds of subsection functions input by user are completed, the images of the corresponding functions are drawn and the function values are given only by clicking button.
