图形用户界面（GUI）演示常见的二维函数图形。菜单条中含有5个菜单项：Plot、Option、LineStyle、Color和Quit。Plot中有Sine Wave、tsin(3t) Wave、2*exp(-0.5*x).*cos(pi*x) Wave、四页玫瑰曲线、阿基米德螺旋曲线和心形曲线六个子菜单项，分别控制在本图形窗口画出相应曲线。-Graphical user interface (GUI) shows the common two-dimensional graphics func

采用matlab绘制累计频率曲线，嘿嘿，虽然是很小的代码，但是很有用哦-Using matlab draw cumulative frequency curve, hey hey, although it is very small code, but very useful oh

利用MATLAB编程绘制相应的曲线，利用相关控件实现-Using MATLAB programming to draw the corresponding curve, using the relevant control to achieve

对一组离散的数求导，并画出离散变量的曲线和其导数的曲线(The number of a set of discrete derivative，and draw the curve of the discrete variable and its derivative curve)
